If you're talking about this board, I wouldn't agree with the "well rewarded" part.
Part of the problem is a pretty good portion of what you post is talking about yourself. There's just about always a line about "oh, I did this" or "I know all about that" or some such. It's generally pretty clear you want people to think you're a big deal. When they don't, you get pissed off.
The fact that you make so much effort to try and establish yourself as superior to me is particularly amusing...and telling. I'm just an average fan and don't claim to be anything else, but apparently I make a "retired college coach" insecure.
Some of us - probably a lot of us, actually - are both capable of and comfortable with talking football without having to tell everybody we're something that we're really not. Message board rep isn't such a big serious deal. The average fan here is just that, and is fine with that, and doesn't need to go out and try to tell everyone how great they are.
As the saying goes, if you have to tell me how great you are, you're not.
Likewise, if your need to make people think you're a big deal to get them to listen to your opinions, then your opinions aren't that great.
