No it doesn't really bother me. I don't often look at how many views the threads get. I'll quite often read a thread and although the post is quite funny or has adorable pictures, or whatever; I really can't think of anything to say. After a while you feel a bit of a fraud saying "beautiful pictures" all the time - even though you honestly mean it. Also, unless you are quite early into a thread, the chances are that someone else has already said what you were going to. If you don't take the time to think of a reply to that thread, then you have more time to perhaps read a couple of threads that you wouldn't have got to otherwise.
