Nope, tweets with all the right hash tags over a few weeks. I got a favorite and maybe a follower on somewhat random remarks, but usually nothing.

Just because you yell into a cave full of people doesn't mean you'll solicit a response.

On this point, twitter is not designed to facilitate conversations. Twitter is a wall of announcement megaphones sort of thing it seems.
