Stack Overflow's new Gaming site is in public beta

Now - even though technically they should prefer openid over normal login - that doesn't mean they'll roll with it. There is a lot more involved in making a decision when it breaks convention like their login.
Clearly I prefer the direction that HN and most other startups are going - away from openid. I don't like or agree with limiting users to openid for years old 'industry politicking' reasons. But in the end I use the content and don't give back, so the loss is on the community and site not me. On most stackexchange sites that don't have critical mass, simple decisions like this can still cause a huge problem.
EDIT: Grammar Syntax ...
Jeff has posted some stats (kinda dated now) about the utter dominance of people using their existing Google ID to log in with:

Ironically most of these questions should be directed at producers and designers not developers. Yet the catch-all name sticks.

After the private beta, there is a 60-90 day public beta. The purpose of this is to make sure the site really survives and doesn't just get a burst of activity and then disappears. Sites which still have a lot of activity at the end of 90 days become permanent sites... sites which don't would be closed down.
The public beta also allows a community to start to develop.... in addition to setting a tone for the site and deciding what kinds of things are on-topic, they work on picking a permanent domain name, a logo, a graphic design, and electing moderators.
