If people view but don't post anything in reply, doesn't it just imply that they aren't interested enough in the post to have an opinion either way? That's how I would interpret it. It doesn't only happen with your posts, why take it so personally?

eg the Black Friday Shopping Madness thread has 76 views and no posts. I looked at it but thought it was too stupid to warrant a reply. Lots of people obviously thought the same.
