Exodus, we all take the good with the bad. I cannot imagine any other message boards with more useful information than ET. Sure there's bashing but what message boards don't have that? Not everyone will get along and not everyone is on the same side of the market. Raging Bull nor Yahoo messageboards never had this much quality information and posters in their 1 decade of existence and those are the only viable competitor I can think of.
I think you could improve the quality even more by having a ET member age limit of at least 21. Old enough to drink, old enough to post.
Same one you posted the link to in your second post to ET: http://www.elitetrader.com/vb/showthread.php?s=&postid=1064216#post1064216
