My local congressman, also a co-sponsor and co-author of the SOPA bill, held a public phone conference the other night. You could press 0 to enter a queue to ask a question, so I did, but after 2 hours I was tired of waiting and I had a term paper to write so I gave up. I kind of regret it now, because I wanted everyone to hear just how little he, a co-author, knew about the subject. He's not one for listening to his constituents. I had already written him a letter and tried to call his office and no reply for either.
I always get replies from my Congresspeople. Unfortunately, they're usually along the lines of "SOPA will save America from sinking into the ocean" or some similar bullshit.
