For over a decade, the hashtag #Edchat allowed educators using Twitter to gather, share, and commiserate. However, as the platform formerly known as Twitter transitioned into X, the landscape of this digital discussion site shifted dramatically. Drawing from recent research, this post explores how educators have used #Edchat over time, the stressors inherent in this social media use, and the history of a community in transition. Researchers understand that for a variety of reasons, Twitter and Twitter chats are far less influential than they were a few years ago. They argue that studying the edchat phenomenon historically may have value for other social media platforms generally and specifically, should they hope to involve educators.
The Golden Era of #Edchat: Purpose and Participation
In its prime, #Edchat provided a means for informal professional development. Research by Willet (2019) and later Willet and colleagues analyzed hundreds of thousands of tweets to understand exactly how and why educators were using the platform. The study identified several key types of engagement:
- Resource Sharing: The most common use case, where teachers curated and distributed lesson plans, EdTech tools, links, and articles.
- Pedagogical Debate: Scheduled weekly chats allowed for deep dives into specific topics, from classroom management to the integration of AI.
- Social Support: Perhaps most importantly, it provided a space for “digital social support,” helping teachers feel less isolated in their professional struggles.
This era was defined by a sense of “augmented intelligence,” in which the collective knowledge of the network enhanced individual teachers’ expertise.
2008–2014: The Golden Era of Synchronous Twitter Connection
The #Edchat phenomenon began in October 2008. This early era was defined by the weekly Tuesday night chat, a highly structured synchronous event that became a must for thousands of educators. An agreement on Tuesday night did not result from any official declaration, but once started, Tuesday night became the default for those wanting to participate in a common chat.
I encourage anyone interested in the topic of teacher use of social media to read the two references to Willet and colleagues I provide here. These researchers had access to what I have heard described as the Twitter firehose, which was available until 2023, and downloaded over 15 million tweets for analysis using the #edchat hashtag as used over 15 years. Unlike researchers who implemented projects of a much smaller scale and made use of human raters to classify and quantify characteristics of such chats, Willet and colleagues used data analysis tools that quantified specific characteristics (questions, responses, links, secondary tags, retweets) and even tools that attempted to identify themes based on terms appearing in the tweets. These characteristics were mapped against years to identify trends.
This approach allowed certain questions that could only be addressed by this massive scale. What trends could be observed over the history of the edchat phenomenon, but may have been overlooked in the data? For example, the way in which edchats evolved interacted with the capabilities of the Twitter platform. Tags were a user-applied innovation that was later integrated into the tool as a capability. Tuesday night became the impromptu time for edchats, which took on a formalized approach. A chat leader would provide a series of prompts identified as Q1, Q2, Q… and participants would respond using R1,R2, R… . Other tweets could be added within the rough synchronous time frame defined by the prompts. Because chats were stored, others might review the session at their leisure and add their own contributions.
Just to be clear for those unfamiliar with the reason for this format, this experience was based on a kludge of sorts. By searching for #edchat, you could follow the sequence of questions, responses, and related comments in real time, separate from other Twitter chatter. The hashtag functions as a sort of portal, focusing Twitter use on the chat content and turning Twitter from an asynchronous to a synchronous tool. Tools other than Twitter, such as Tweetdeck (no longer available), even allowed users to create a multi-column display, with individual columns focused on specific tags and updated automatically. Only the #echat contributions would then be displayed within one column. These tools became popular as an easy way to turn the Twitter feed into a synchronous experience unique to those using the #edchat hashtag.
Research shows that between 2009 and 2014, these Tuesday sessions saw significantly higher engagement than other days, characterized by genuine dialogue and a high volume of questions and replies. Teachers weren’t just “knowledge telling”; they were building communities of practice and exploring new pedagogical ideas in real-time.
The researchers had a special interest in the frequency of questions and replies, and the ratio between the two, assuming these variables would be a good way to assess interaction. In addition, how did these variables differ between Tuesday and other days, assuming this would be related to the higher likelihood of synchronous interaction on Tuesdays? Replies made up a higher proportion on Tuesdays and were significantly higher in the earlier years. My interpretation differs from the researchers’. They argued that there was a decrease in interaction in later years. My interpretation is that the chats drifted away from the formal structure of questions interspersed with participants’ answers. Relying on the massive scale and automated methods employed rather than human raters following the give and take of individual sessions may have led to different interpretations.
2014–2018: The Shift from Dialogue to Broadcasting
At its peak in 2017–2018, #Edchat was a massive digital footprint, averaging 120,000 tweets per month and involving roughly 200,000 different users. However, beneath these impressive numbers, the nature of the interaction was shifting. Starting around 2014, Willet and other researchers observed a transition from authentic conversation toward broadcast-style communication.
Several key trends marked this transformation:
• The Rise of the Link: While early chats focused on natural discussion, later years saw a sharp increase in posts containing hyperlinks to external content, suggesting the platform was becoming a repository for resource sharing rather than deep discussion.
• Retweet Dominance: Retweets began to outnumber original posts, and the percentage of questions receiving replies dropped significantly. Retweets could be used by individuals to bring those who followed these individuals but were not chat participants to experience the content.
• Exploitation: As the hashtag grew in popularity, it became a target for spam and self-promotion. By 2018, the community faced a spike in problematic content and a decline in “authenticity scores” as commercial interests exploited the tag for marketing.
The transition to less interaction and greater influencer dominance may also be related to the active/passive distinction that researchers have begun to study in social media activity. A focus on Twitter chats as a source of resources is consistent with this research topic.
You can still find the use of #edchat on X, Bluesky, and Mastodon instances. The tag is typically used now to indicate educational content and is seldom used in the same way within a chat sequence. A few chats can still be found, often now, using more idiosyncratic tags.
The Paradox of Digital Support
I wrote a series of posts beginning in 2013, focused on edchats, mostly questioning the information value of the process. I appreciated the camaraderie the chats offered, but the limit on the number of characters Twitter allowed, along with my reaction to the content included in such chats, led me to believe the experience was very inefficient, and I thus proposed tactics I thought would increase the professional development value of the experiences.
Edchats were often included as one experience within the grad course on technology class I taught, and I proposed, without success, that students might analyze the content of such chats as a potential thesis project. My suggestion at that time was that video-based systems (e.g., Skype, Zoom) would allow a much more productive approach.
2018–2023: Volatility, X, and Fragmentation
The decline of #Edchat accelerated after 2018, driven by platform volatility and the eventual transition of Twitter into X. Changes in leadership and algorithm priorities disrupted the organic reach of educational hashtags. As the environment became more polarized, many educators began to migrate to other platforms like Instagram, Mastodon, or niche, specialized communities that better served their specific needs.
By 2023, the once-unified #Edchat community had largely fragmented. This decline highlights a critical vulnerability: digital spaces on commercial platforms often lack the stability and continuity of traditional professional development. When profit extraction and algorithmic shifts override user experience, the community suffers.
Lessons for the Future
The history of #Edchat is a reminder that while platforms change, the human need for collaboration remains constant. The legacy of this 15-year experiment suggests that for future digital communities to succeed, they must:
1. Prioritize Active Participation: Moving beyond passive consumption is essential to avoid the stress of social comparison.
2. Foster Authentic Dialogue: Successful communities require mechanisms that encourage genuine interaction over simple content broadcasting.
3. Shift to Knowledge Building: The goal of any digital faculty lounge should be to move from merely “telling” knowledge to collaboratively building it.
Perhaps online interaction among educators isn’t gone; it is simply evolving. As educators move toward new tools, the story of #Edchat serves as both a testament to the power of digital connection and a cautionary tale about the challenges of sustaining authentic community in commercial environments.
I have tried to identify where those educators interested in online interaction with peers went. I could not find the type of quantified data provided by Willett, but other researchers (Greenhow and colleagues) have suggested that Facebook groups and Instagram have become favorite sites for interaction.
