Thanks for the feedback, I'm the other co-founder of Crowdlink. We see our service as more of a complement to Gittip, where the monetary component is more of a way to show the developer you would really like to see a feature and give a small tip, instead of trying to live off of it. I know if I was dragging my feet to fix an annoying bug and a couple people put up a dollar each I would feel motivated because I knew that people genuinely valued the work.
