Congrats on the open letter. Have you also tried emailing, or writing a real letter? I have gotten a few personal responses from well reasoned emails I have sent, including one after seeing my senator publicly change his position in my favor. They really do listen. An open letter is mostly just going to get other people on the internets to agree with you.

Oh, and if you are going to fight for less regulation you might want to wait for the only BTC news story in the popular media to blow over.
