Add recruiting.la

I don't know if I like or hate that they used a mailing list service. It's extra
insulting, but there's an unsubscribe link. At any rate, he led with this
nonsense:

> Your resume needs mobile social video experience.
>
> Why?: Developing a platform API for developers and mobile video experiences is
> the hottest experience you can get.  Viddy and SocialCam are exploding -
> adding 10M users a week - but they don't use Rails.
>
> Use Rails at my client to take social video sharing to the next level.  My
> client is well funded, has an app with traction and a great UX and is
> currently building its public API.  Also, they are entertainment and celebrity
> focused - a rare opportunity in SF.
