There is lots happening out there. I had my attention drawn to the Eduserv Virtual World Watch (VWW). Eduserv and VWW have just published a "snapshot of virtual world activity in UK Higher and Further Education", available here. No single conclusion from the report, but an account of an incohate, coalescent sphere of frenetic activity and much more to it than Second Life.
Another incohate, coalescent world is that of global capitalism. I went looking for alternative political voices in the context of the current global banking blip and didn't really find any, except Graham Attwell asking a similar question. I did find two interesting social networking software developments: from Rise Up (crabgrass) and the World Social Forum (OpenFSM), but no clear calls for an alternative politics.
I am writing this, however, because of another novel, incohate, coalescent world. These and many more items came my way through Twitter. Like John Pallister (here), I have become a cautious addict. Have a look at Martin Weller's Camtasia creation "A Twitter Love Song". Bruce Ingraham would have loved the form and the argument. The open api has led to many Twitter-related sites and applications, some are: Twhirl, TwitPic, Twemes, Twiffid. Twiffid scrobbles the blog addresses from the people you follow on Twitter, and presents you with their latest posts and, even better, the rss feed so you can read them in your favorite reader. Mine is Fresh, these days. I wrote about Fresh here. John's Twitter stream led me to CoolCatTeacher's blog about 5 Twitter Goodies to get you a-tweeting.
I am daily amazed at how much creative energy there is cohering in the Internet.
