Here's my outlook on some of the more common misunderstandings of freeoll tourney players at AP (and probably other sites as well)....
1)
all-in "idiots" at every tourney's start. Ok, I'll agree that some of these peeps may not be all that disciplined. But hidden in their ranks is some very smart play. Just picture it... you are registered at so many site that you have freerolls starting every 10 or 15 minutes. I only like to play 4 at a time (on a modem, sorry all heh) so why would I spend possibly hours trying to build up a promising stack? If I go all-in every 10 or 15 minutes, sooner or later I will go huge in some game. NOW I have a stack I'm ready to work with and am even more ready to go all-in in consecutive games while working the lucky one. I'm not advocating this style so much as explaining why it isn't always such a dumb move.
2)
what a stupid play. This is more obvious than the last one but still happens over and over. Someone does something stupid and someone else starts going on and on about how they should have played smarter. The "stupid" player could be exhausted (in any time zone), drunk, hungry, bored, etc etc etc. I would say that actually, you should expect very ignorant appearing play at any time while playing online. Not doing so makes YOU the dummy

Besides, when I see someone begin to go off I think 1 thing... tilt=more chips for me. Here's another idea, when someone gets lucky on a dumb move, compliment them. Maybe just a "nh" or a "wow, good move", pretty much anything that encourages more stupidity preferably without setting off other players. Never "tap on the glass" and tell players what the "right" move was.
