Many of us are familiar with http://bash.org, or have our own Google doc full of funny things people have said in IRC, Campfire, et. al; my friend and I put together a free service where you can create your own quote board.

Boards are public by default; you can set up a whitelist to keep things private, and set mods and admins who can administer quotes and board settings. You can also set up sub-boards, such as "x.qotr.net" and "z.y.x.qotr.net"; permissions and quotes are inherited.

It has an API built in as well; you can make requests with a token you are assigned on your account page after sign up. It's a RESTful interface, so you can get/post/put/delete quotes to boards.

It uses PHP and MongoDB, hosted on EC2. We built this mostly in a weekend, and open-sourced a PHP framework that came out of it at http://github.com/Olivine-Labs/Mint (although we need to, um, build documentation and examples.) We're working on rebuilding and vastly simplifying Mint as well, over the coming months.
