I'm doing it. I wrote an ultra rough spec one month ago, tried selling before building, found that only 1 person out of 20 or so that I thought it would be relevant was interested, am refining again. It's been about a month, we should launch in a week or so. This probably won't be a huge company, just looking to make around $75/active hour for 20 hours per week for the next year or so whilst longer range projects grow slowly.
