over time, most forums i have posted at have simply outlived their usefulness for me by getting too big, too crowded. have had the same experience with bars in my life. i prefer the smaller saloons, perhaps 'quaint' is the right word. there was a bar in houston that the mrs. and i really liked. could always go find some regular to chat and share a cocktail with. occasionally there would be a bigger crowd on friday-saturday and maybe once a year a fight/shoving match would break out, but for the most part everyone was friendly and respectful. then it started to become more popular when a new office building opened up in the area, lots of loud-mouth starched shirts showing off their obnoxious and arrogant sides. we eventually just quit going and found another place to enjoy.
have done the same thing at various sports or gambling message boards over the years. many just started to be places to hurl smack talk or otherwise insult each other instead of exchanging good info.
