You cannot believe how many memberships I have in social networks, maybe around 20. The best so far, in terms of non-profit support and active participation is TakingITGlobal. I am a member of Care2.com, (a social network like TIG but supporting environment issues) but I found the site a little bit stifling, in terms of encouraging creativity. Most members just cut and paste posts from other news portals.

I am beginning to think that I should give it up for more important sites like the up and coming Melt Campaign of Greenpeace.
