I know of a few guys who regularly play in it. The 'skill league' actually has GREAT prizes on their leaderboard (monthly I think?). It's getting qualified that might be a pain in the azz though (they all qualified the first time it ran & did so via freerolls). Tried one or two myself but didn't have the patience for it.
There's some not too bad vids. there on PSO that you can view for free (some you need to have earned a certain # of vpps (or fpps?). Many of them are worth viewing.
There's also another promo thing there with PSO. There's a monthly $10 buyin with $1,000 added to it (it's actually running tomorrow 16:30est). They have satellites running every day of the month for it, some with a few seats added (50cent buyins, & $1 buyins, some freerolls (i think?) too.
The play in the monthly $1K added final is pretty horrendous (prob due to all the entrants who got there via satellites) but the extra cash in the prizepool does make it enticing. There's also a handful of decent micro MTT/SNG players in it too. (it's pretty much a minefield though... sort of like the OFC games.. but maybe a bit worse).
There's also a women's league on Stars these days. 4 games each day (2x 10cent, & 2x $1), each player can play 1 of each per day. There are leaderboard prizes in this league too. (guys are ineligible for prizes though obviously)
