Elon Musk’s successful purchase of Twitter and the questionable behavior that has followed has caused users to quit or at least seek an alternative. I am waiting to see what happens and I would be reluctant to leave until after the election season has passed. This seems a critical time and not the time to withdraw. I am also concerned about heavily populated silos and then impact on individuals who receive little else in daily information. This is the reason I have joined and regularly comment on Truth Social.
I am a member of two alternative social platforms – Mastodon (twit.social) and WT.social.
Here are a couple of sources you might explore if you are interested in alternatives.
