Here are some things that posters may be doing without realizing it.
Some posters (I'm not pointing this at anyone here). Do not seem to recognize when they are insulting others, and then wonder why they get smites.
Refering to users by a derogatory term like Fanboys is one common denominator.
Putting other users into a class of people who are not experts like the poster is.
Posting, I am going to do XXX if Canon does not create the camera I dream about is boring, and do it enough times, and its irritating. It kinda falls into #2. I know better than anyone else.
Ideally, posts should be thoughtful and provide some positive information rather than incessant whinning. That comes accross as childish. Its not a ideal world, but I wish some would not troll the forum trying to stir up others with childish comments.
Then, there are those who smite others for no good reason. Just ignore them.
+1 for all the recent posters.
