Why is it on these message boards?

[AZnuts]

I've recognized a pattern, similar to the recent posts about "why so much hostility" on these boards.

Generally, many of the respondents who are the rude, flaming, sarcastic type have very few of their own ORIGINAL threads. They like to lash out at others, but have very little new content of their own.

Is it that they are omnipotent on poker matters, or maybe they don't have the courage to risk ridicule by posing a new thread, since they know the kind of crap they dish out to others?
