How many people use steam?

I would like to get a count for how many people on here actually use steam. If you do use steam what sorts of games would you like to see us support for competitive gaming. Also could you post your steam ID. My ID is Spence5060. Once we get enough members on steam we could start expanding with steam groups and the such. This will be the official community list to show all steam IDs for everyone that has steam.
