Viraliti is a “paid to pin” site. You can create an account and look for things you can pin to your various boards on Pinterest. If anyone clicks through to the advertiser's website from any of your pins, you'll earn a certain amount per click. I have been signed up with Viraliti for several months now but haven't used it enough to get a payment. Currently they pay with Paypal and you need $30 to get paid. Payments are processed in the 1st and 16th of every month. It looks like they are currently in private beta, but you can request to be invited.

As users engage with these electronic services, they create highly interactive platforms through which individuals, communities, and organizations can share, co-create, discuss, and modify user-generated content or pre-made content posted online.
