Just noticed a moderately nifty feature. If you close an IM, when you click on that person's name again to recommence speaking to them, it immediately pops up the saved conversation. Sure, it's just message archiving and I'm not surprised that anything from Google has an archive, but it was neat to see the old conversation just instantly be there, to be picked up where you left off. Since I'm not one to leave conversations open once a person has logged off, or even if the conversation has stopped, I often forget what was said last should a person return and reply. That's moderately handy.

I skipped the first one since it's just the guy begging people to stop inviting him to their GT buddy list. ;)
