Yeah,I Must say that!
So.cl is quite different from Facebook and Google+. Infact i find it quite interesting and innovative!
The 3 main features of So.cl are quite awesome, and are not there in any of the present social network ( except the last feature video party).
FYI, The three features are
1) Share your search
2) Create a post that is full of rich media ( yeah i am talking of a image+ video+ webpage + ma personalized status update all in one post)
3) Video party
It would be interesting to see how Microsoft will promote So.cl in coming days.
