This!!! I've noticed how "forums" (as opposed to reddit-style discussion boards which are moderated) tend to have this sort of "first post!11!!!" behavior. If you look at that user's post history, he or she has contributed, but - also is providing lots, and lots of commentary. And while that commentary is useful, it's not necessarily moving the ball on solving whatever the problem of the day is.

I see the same thing in travel forums frequently.
