For the non-Americans here, Pokerstars just released Zoom-beta, basically their version of Rush Poker* from Full Tilt. The bad news is that only micro-stakes tables are available; the good news is that everyone is donking around like Jamie Gold.
*It's a fast-paced poker game that instantly allows players to move to another table as soon as they've completed their action. So, for example, if you're in the cut-off with 72offsuit, you can fold before it's your turn to act and you're placed on a new table with a new hand.
