There's a lot of hate being thrown Yammer's way because it's a twitter-clone, but I thought Yammer was brilliantly executed with additional layers of their own innovation. They have what Twitter does not: a very viable subscription model. Could be a nice acquisition for LinkedIn if you ask me.

I do agree though with the general consensus that it should not have been the winner. I thought OtherInbox was leaps and bounds more innovative.
