Some time ago, the Reddit community expressed their interest to have an @reddit email account (they were willing to pay for POP access, etc.). I tried to contact the Reddit admins by Reddit messages, email, Facebook, etc, because we can provide them with @reddit mail accounts in no time and scalability is not an issue (we have installations in some of the biggest ISPs in the world) and it would cost them nothing as we were wanting to do a rev-share deal. Sadly I never heard back.

There's an opportunity to monetize Reddit users, even if they seem somewhat far from the core product.
