As promised, we are slowly rolling out the third place across our network... even for ewoks!
In addition to
chat.serverfault we just brought up chat.superuser.com:
|`superuser.com`||Q&A; for computer enthusiasts and power users|
|`meta.superuser.com`||community organization and discussion about the site itself|
|`chat.superuser.com`||real time chat "third place" for regulars|
Although chat.superuser.com is technically another public beta, we're still on track for releasing chat network-wide in a few weeks. However, stackoverflow.com will be the last site to get chat because its immense volume presents the hardest challenge.
We're hoping to get good feedback from chat.superuser and chat.serverfault before proceeding onward, so please -- jump in and tell us what you think!
