Impressive performance and clean design. /me interested.

I don't understand the need to claim such a broad copyright license on content submitted.

"When providing us with content or posting content on Moot’s site or related third-party sites, you grant us a non-exclusive, worldwide, perpetual, irrevocable, royalty-free, sublicensable (through multiple tiers) right AND LICENSE to exercise any and all copyright, trademark, publicity, and database rights you have in the content, in any media known now or in the future."

The "Why do we have this clause" link doesn't feel like it answers that either.

Also, the "Following is guaranteed" bit needs work. It sounds good, but is legally worthless, I expect.
