RTB is an ingame mod, it only interferes when you're actually using it.
Teamspeak, I believe can just be run in the background and still work.
TBB is a website, if you even care enough to follow it, you'd open it maybe once a day or so then close it again.
Steam is an overlayn application, as such it's like RTB in that it won't interfere.
Also, I do have problems taking a talking vehicle seriously, sorry.
