Well, you are basically saying don't waste time referring people to Dropbox given their incentives. I did this trick a few weeks ago when Vladik initially posted. Cost me $13 in total (+ about 10min of my time) to go from 2.8GB to 10.8GB. Followed instructions to a 't'. Although the 2nd day I bumped my min up to $0.10 - got click-throughs a lot faster, but I would recommend staying at the $.05 max.
Pure ROI, say I could have billed $30 for my 10min + $13 on adwords - then amortize over 4 years (assuming thats how long I would have my free 8GB with dropbox). I get my 8GB for $.90/month. Its no steal, but that is a solid deal.
Of course, now that this technique hit HN, I would expect the adword prices to go up. Great hack Vladik! Thanks again for sharing.
