'partypoker is hard to make money'

[Meatmaw]

A friend of mine was telling me how her roomie's boyfriend quit his job to play poker online, flying to vegas, etc and runs a gaming site. One thing she mentioned was that he said:

"It's hard to make money at Partypoker because a lot of beginners play unpredictably. He only plays high stakes."

I laughed at this initially, but then it got me thinking. I don't know if this pertains to limit, NL, SNG, ring, or all, but do you guys feel that completely unpredictable bad players might be tougher profit than perhaps 1 level up at predictably weak or some other breed of player? Was this guy alluding to players at Party just being *so* bad that it was more profitable against more informed amateur players? What do you think?
