I think Greg Raymer contributed to 2+2 going downhill. For one thing, before he won the WSOP, he regularly posted on the tournament strategy boards, now his time isn't his own anymore. Second, when he credited the forum for helping him improve his game, it exploded in poularity. That popularity has not only watered down the advice given, but much of the site has become a little too incestuous and cliquey for my taste, There are still some really strong people there and (contrary to what some bloggers say) the best advice there is from people who aren't Sklansky-Malmuth clones. It's just tough to wade through the crap to find the good stuff.
The tournament series (called King of the Zoo - see 'Stars private tournies) run by 2+2 posters (not endorsed by the site) is in it's 3rd year, is well-run, encompasses all forms of poker even-though the NLHE-only crowd does whine a bit, and all-in all is reasonably challenging.
I only say this stuff because a lot of people who've gone to the site lately put it down, and for some very good reasons, but for a long time it was easily the best place to learn. People rag on it because they see some bad advice there. What they fail to understand is that the best way to improve your game is not to just read a book, but to actually dialog about what you're trying to do in certain situations.
One of the reasons that I like posting here is that there's the opportunity for this to becaome the kind of community 2+2 used to be before success gave it a big head

. That and there aren't any links to poker sites here so it gets through the blocking software at work.
I've made some good poker friends there, and while I like reading blogs, a blog doesn't offer the opportunity for real interraction and discussion. I've been sending some PM's to some of the better people from 2+2 to come check this site out. They'd add a lot.
