Yeah, so what exactly is it doing in 12.10 when it "installs facebook" or "installs gmail" or "installs google doc?"

Is it just an app that interfaces with one of the above API's to give you information such as message count?

If so, do they have any controls? I mean I see you can 'control' stuff in the 'Online Accounts' sub-section of the settings, but there's not really any controls there besides empathy integration for each of the accounts.

I noticed it'll add something to the Unity sidebar, and clicking it will switch to the tab in the browser...but that's about it, any other purpose I'm missing?
