We'll be changing the look and feel of the site over the next week or two.
All the text and banners will change to say "saidit.net" and that will become the new URL. We will move away from the name antiextremes and eventually retire it after we're completely transferred over to the new name.
D3rr has added the chat in /r/all. He also added it so that newly created user accounts are by default subscribed to all subreddits. This way more traffic will be exposed to more posts, which should help the site grow and be more interesting to new users.
