I am a regular forum reader and post somewhat often. I like reading most of the points some make and some of the ignorance of others. What annoys me most about these forums is all the people claiming this or that as fact. You come off looking like a jerk. "You are wrong, no YOU are WRONG." Please, both are stating opinions, which means nobody is wrong. Make your point, as your opinion and stop bashing someone else's opinion as though you are giving pure fact.
That is all.
(FYI, it seems some of the more prominent forum posters do this constantly)
