I frequent them for information, knowledge and humor.
Humor is/was a major reason people get kicked of the above mentioned forum. There was a great poster, full of info that he shared freely, (not necessarily a common thing on a fishing forum). He was a teller of stories too. He wrote a humorous story about the ducks in his back yard. In the story he surmised that one of the ducks might be gay. That was pretty much the straw that broke that camel's back when he was called to task for guessing that a duck, might be gay. And typing it out on the forum.
The site also has a long list of words that aren't allowed....Nazi, Tweeker, Squaw fish and others I can't think of now.
