Today and tomorrow I am attending the Mesh conference in Toronto talking about Web 2.0 issues. Jim Milles is here, too, blogging beside me so you might check out his blogs for additional perspective on the issues raised.
Day 1 is largely focussed on social, political and broadcasting/media issues. Day 2 (tomorrow) will have a more business / marketing / entrepreneurial focus.
One of the organizers is Rob Hyndman, so there are definitely legal issues are being addressed in the sessions.
The conference is being held in the funky MaRS Collaboration Centre on College St. (just west of University Ave.) research / start up space with business offices and conference space. Very very cool.
