Picoworkers is a microworking platform where you can perform small online tasks for small payments. It’s a similar platform to Clickworker (review here), and Amazon Mechanical Turk.
Picoworkers is a two way platform. Once you set up an account, you can both perform small tasks for money, or pay people to do micro-tasks for you.
For example, if you were keen to get more people to follow your social media accounts, or to join the mailing list for your blog, you could pay them to do so.
