EDIT: Shoot! I just realized that, by using the word "thread" in the title, I may have mislead people into thinking this is about "threads," as in the threads on a pedal crank, etc. Sorry!

This is a semi-serious question, though not related to cycling.

I seem to be the last word in most of the threads I post to. I don't think I come off like a know-it-all or someone who is not open to other people's ideas. In fact, I crave the opinions of others whenever I post something. Still, I feel like a thread murderer. A thread can go on for six hundred posts, then I say something and everybody leaves the room.

Is it me? Am I being paranoid? Over-analyzing? Or can one of you legit forum members (not one of the trolls) make some suggestions for how not to be the guy who farts in the field and sends everyone scrambling?
