Interesting social site from Philips. I'm not sure how many active users they have (or what social tribes it crosses), but they do have an interesting site. Questions like "is RSS really simple?" Question about DRM. Is time the new currency? Some questions of collaboration creation, which may miss the point. (and yet, depending on how approached, might not). Themes include: Internet & Computing questions, Lifestyle & social (I like the 4 day week idea myself :) - wasn't more leisure time, for whatever purpose, one of the dreams of progress? )
