Good thing So.cl has just been silently launched.
Microsoft opened it's social network named So.cl over the weekend to everyone. Microsoft is positioning So.cl for students and as a research project from its FUSE Labs. So.cl combines search and social networking. So.cl is an interesting concept, but that is all what it is right now.
So.cl does not scale right now. It is slow and when I tried to log in via Facebook, I got a error page, with definitely the cuttest error bug there is - but it is still an error. Inside So.cl you also get greeted with an apology message.
