There are way too many newbies to the game that think chasing to the river every other hand is good basic strategy. ...and with a bunch of them in a large tourney, some will get lucky and knock out skilled players.

I'm also finding that on internet poker, the higher the stakes, the fewer bad players you'll find. A year ago, you wouldn't find me playing for more than 3/6 online because I thought I'd find the same reckless play at higher levels. Now I don't usually play for less than 5/10, and have found 10/20 to be pretty stable, mostly knowledgeable/skilled players. That's how I like it!
