Unlike Translink in Vancouver, TriMet wants to use Social Media in a one-way format, don't bother them with your questions, unless you want to use the form or call. TriMet has been very slow at adapting to Twitter, sending out service alerts late, and just "sorta" using it. Skimming thru the TriMet Twitter they are answering peoples questions and complaints (mine too), but judging by all the attention being given to "Use the form", they do not want to be answering you on Twitter, and maybe they are trying to run from it. TriMet needs to learn from Translink pilot Twitter project, which is VERY successful, it was made permanent.
TriMet has also taken this to Facebook, there are a few very vocal people (that it appears TriMet ignores, because the only respond to those who praise the service).
TriMet: Twitter and Facebook are great ways to communicate with your riders and users, embrace it, don't ruin it.
