Web Game Dev has launched recently. Looks like an interesting resource. They have an affiliate program too. Not sure if that's good or bad, but here's my link for what it's worth.
From their site:
"WebGD (Web Game Dev) is a new site dedicated to bringing people and information together for those who are web game developers or are at least interested in developing games on the internet. Our site brings you the latest web game news, blogs, and forums to discuss your project, or help others with theirs. You can also find the tools you need, or read reviews on the latest tools used in web game development."
I'll definitely keep an eye on it; seems right in line what we're trying to do. And it's powered with Drupal!
[Edit 2007-06-04] Appears they're no longer powered with Drupal. That's a shame.
