I try and play 2 or 3 times a week to stay on my game.
The key to online play really is multi-table tournaments.
Initial feedback we got from people was that Poker could and should be a product in its own right. For us, that was definitely a case of us not seeing the forest for the trees since we are Poker nuts.

Being able to pit your wits against literally hundreds of other people is really exciting and ultimately the biggest single challenge for a poker player.
It is really hard to make it convincing enough that you forget you are playing a video game.
