I am now well in my first month at Yoono, and you can already play with my work by installing the last version from AMO. I have been working mostly on the Facebook integration in the friends widget.
Here are some of the features I added:
Online presence and chat: no chat in the sidebar yet, but you can already see who is online from the sidebar and initiate a chat from there.
Contact sorting: at least for Facebook and Twitter, contacts are now sorted by last updated first

New activity types, from the new Facebook API: you are now notified when your friends post new notes or share links. With the thumbnail:

There is much more coming for Yoono's friends widget in the next version. I can't tell anything for now (Yoono's development is not open), but stay tuned for the 5.5.0!
