I've just been reading Wired's article about SNS for Students and Marc Canter was quoted as saying that the average user was active in 5 Social Networks. I wasn't entired sure if they meant "5 communities" or "5 websites", but, given that they then went on to list 5 sites, I guess it was the latter. (http://www.wired.com/software/webservices/news/2007/08/student_networks ) I've found (I think!) Canter's blog ( http://marc.blogs.it/) but can't seem to find anything about the numbers of active networks. I was rather surprised to read the 5, clearly the definition of "active" could vary, I'm sure my MySpace account that I signed up for ages ago doesn't count, but I wouldn't call myself active on Facebook either (login perhaps once a fortnight, don't actively add friends, delete requests from those I don't recognise etc). I'm also assuming that he's not counting things like forums, which are, in effect, a community, but again, I could be wrong. Does anyone else have any evidence (published or anecdotal) to support or otherwise Canter's claim? Emma -- Blog: http://userweb.port.ac.uk/~duke-wie/blog/
