The big participatory web news of the day (or perhaps year) is Google’s announcement of Google apps for organizations (translate as schools for this audience). The education edition is free. A summary of the concept and products is available for viewing (check out the 12 minute version). Google calendar, docs, gmail, page creator – the collaborative tools – make up the collection. It looks like Google is going to serve as an ISP hosting a branded site for a school (business or individual).
One interesting opportunity within this collection is Google Sites (based on the old JotSpot if I am interpreting the announcement appropriately). Google site offers template-based web development and collaborative. See this linked summary differentiating the Standard, Premier and Education editions.
This looks very impressive. More when I have had time to experiment.
