Recently I've created a twitter account with basic purpose to provide some support for JetBrains TeamCity and Checkvist.
Many JetBrainers actively twit and provide product support as well.

These accounts a pretty new, but in the long run you'll find a lot of interesting stuff in these feeds, I'm sure.
So follow to stay tuned!
Update: dotTrace account has been created as well :)
