As promised, we are slowly rolling out the third place across our network.
You may remember we rolled out per-site metas across the entire Stack Exchange network, as well as for Server Fault and Super User, back in July. So from our perspective, we're completing the experience:
|`serverfault.com`||Q&A; for professional system administrators|
|`meta.serverfault.com`||community organization and discussion about the site itself|
|`chat.serverfault.com`||real time chat "third place" for regulars|
chat.serverfault.com is still a public beta, but we're rapidly closing in on release status. I expect we'll begin a fairly aggressive rollout of chat across all sites within 4 weeks or so -- though do be advised that stackoverflow.com will be the last site to get it because of its immense volume.
