It would be really nice to have a dev chat every few months or so, where different TS staff members could come out and talk to the Glitchen, about who they are, what they do, and what they are up to. Q&A sessions are always fun. This could either be though a podcast call-in thing, or through text chat of some sort (IRC, or in-game). It would certainly be easier if it were moderated, but that isn't necessary. With how active the staff is, it would be a fun way to connect with the players on a more personal level.
From experience with other games, if time is very limited, it would be best if voice is used, as there is invariably going to be some staff that are slow typists, and they can slow down the process and leave less time to make with the Q&A. If not, then assign a fast typist to the job.
