Meebo is causing Chess.com pages to not load.
Sort:
Chess.com is nearly unusable this morning because of Meebo. Chess.com pages load quickly, but hangs connecting to Meebo. Because of this, none of the Javascript on the pages run and I can't play chess. I ended up blocking Meebo with Adblock and everything is working fine again.
I am surprised that you have tied the stability of your site to a 3rd party that you have no control over. Is there a way to turn off Meebo in my account settings? I never use it and the chat in-game is enough for me.
