I miss the baked in social networking functionality of People Hub and Me tile. Now my Me tile is rendered essentially useless. Of I want to post to both FB and Twitter I have to post twice, so it's actually faster to use the dedicated apps, and the notifications have moved exclusively to the action center.
I miss this! I get why they want to focus on apps instead of intregration for advanced features and rapid release. But removing the ability to post to multiple social networks is a step in the wrong direction and should not be too difficult to support. My twitter feed will die now, there is no way I will jump around apps to post updates.
This really SUCKS.
