Look in the top right, there's a search box. If you click the drop down menu you can choose "On my mind..."
Whatever you type in there goes to that thread, like a twitter feed I guess. It's locked because conversations aren't really supposed to happen there, that's what "post what's on your mind" (badly named, since it's really turned into a continuous conversation) is for, which you'll find in the rec room.
The twitter name is bad really since it has nothing to do with actual twitter. It's just a similar setup kinda.
