I think that many around here question too much others' posts, ideas, intentions, ... and less themselves. Browsing through ET's threads is worthy enough for me to put up with the relatively large number of worthless and / or rude posts. I pity ignorance, I dislike rudeness, and I despise rude ignorance. Fortunately there are some knowledgeable and nice posts too.
More to the point, are you just a gratuitously abrasive asshole, or do you have a point to make, with supporting evidence to back it up?
I believe this: http://www.elitetrader.com/vb/showthread.php?threadid=63202 Is an example of what good market commentary/strategy discussion is. Bolter explained everything fully, posted his comments in a timely fashion, and even followed up to questions. No one is expecting people to give away their deepest trading secrets, but more threads like the above one would certainly lend to the community.
