It seems that Mysites 2010 falls well short of the mark when it comes to the newsfeed. No out-of-box ability to hit reply, to answer a question, or even to 'like' an existing comment. This is a real discussion killer.
Because of this we are already looking at alternatives which allow for proper enterprise microblogging and functionality (Yammer or NewsGator being the most likely candidates).
Just wondering if anyone has yet attempted to customise the newsfeed and add some of this core microblogging functionality? I'm wondering if customisation is a path worth considering. On the face of it it does seem a daunting task, as the built in data structures don't seem to support threading at all. So we'd be likely be building everything from scratch.
