Update Sunday mid-day: Apparently, chat is not working for everyone still. There's been no official update as of noon my time Sunday from either JTV or Twitch other than Friday's blog posts.
Update Sunday night: The chat problem seems to occur for those using subdomains, i.e., non-English versions of JTV such as es.justin.tv. While I'm sorry that anyone is still having a problem, that does bode well for our cast Monday night. I'm sure very few of our viewers come in via a subdomain.
