It used to be good, but too many participants on the social media bounties now, not really worth the time and effort. As someone mentioned above, you're better off finding the projects independently, can get a far better return and be more selective with the projects that you choose. Wasn't impressed with the return on article writing either, I realise it will always be subjective, but they seem to suffer from tunnel vision. I still check it out now and again, but very rarely get involved with any of the projects.
