Bloggers have a different motivation to blog than a commenter to comment. We have heard of "top bloggers" but have we heard of "top commenters"?<p>My questions are<p>1. Why do people comment on an article?
2. Why do they invest time in doing something, which they may not be able to retrieve later on?
Sometimes I have something to say that I think people will find helpful. Sometimes people reply to my comments with useful information.<p>Feedback is important for everyone.
