This simmering thread http://forum.rpg.net/showthread.php?s=&threadid=48674 on the rpg.net boards has caused a blinding beam of light to strike. Especially this comment, on the fourth page.
"What's happening here is that the gaming club attracts people who are interested in acquiring new players, gaming with different people, or starting new games. However, it completely ignores everyone out there who already has their friends in an ongoing game and doesn't feel the need to advertise one way or another. This applies to the gaming club, but also to whatever other methods you've used to meet other gamers. No matter what you try, you're not going to meet all the people with a casual weekend game with their existing friends, and these are the people who make up the lion's share of the gamers mentioned in that figure."
