My first thought upon matter was : "Wow! Whats that? Did Microsoft built this?"
Yeah,this is a Research Project in Microsoft Labs.They did really good job.i really really liked it.
Normally i dont express my feelings this much for any product but this social network drove me crazy :)
The most awesome part of So.cl is,all your contents are global.So.cl,according to me is a "Thumblr-Facebook-Twitter-Google+ mix".
And thats awesome! Plus, i see Metro like Design which they call it "Riff" in So.cl.
Please experience it yourself,share your valuable thoughts with me.i really like to know what others think about it.
