It may be that Twitter didn't list your tweets in the search results. That's what happened to my first tweet, which is apparently an anti-spam measure Twitter employs.

Knowing no one else who used Twitter, I had no other use for the service and promptly logged off permanently.

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.

Maybe you could easily have engaged conversation with other people on twitter?

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