Their efforts might have borne more fruit if I could have actually paid for the tips I owed. Every time I clicked on a link to pay them, I'd get an unhelpful error message along the lines of "The cash-out feature is temporarily down for maintenance." This situation either lasted for a couple of weeks, or was broken all three times I tried over that period. I thought Tipjoy was great in concept, but ultimately they didn't seem to have either the technical or marketing chops to go up against other systems like Amazon's.
