Betting on poker tournaments

[bholdr]

I know that it's gotta be -EV, given that the odds are never that good, but i almost put a few bucks on negraneu in the WPO this week, mostly because i have a bodog account now and felt like gambling a bit, not because i thought i could profit. they had him at 30-1 (which is pretty bad for a poker tournament, but at the rate that this guy's winning lately...)

and he's in like 20th place right now.

what's the consensus on poker betting? worthwhile at all, or total crapshoot?
