How do I find out what games are available and how many tables are active at each online site?

Poker Site Scout is an independent poker tracking portal showing up-to-the-hour counts of real money players and games from many of the top online poker rooms. This is in contrast to the numbers that the sites themselves advertise, which include play-money and freeroll players. In addition to the player counts you can see a break down of the types of games at each site (e.g., holdem, omaha, and stud). There is a details page for each of the poker rooms covered, and historical data for peak usage by day over the last few months.
