I talk to people who have problems. (I recommend meatspace for this since if you just go to HN or Twitter you'll tend to select the problems that people on HN or Twitter have, and they'll say something like "I am really involved in too many social networks and need like a meta-social network, with RSS feeds and Twitter integration", and you'll go off and build something that will never be used by someone without a Twitter account which, by last count, excludes 99.9% of the population of earth.) For my personal project, I solved that problem. Finding time was a matter of looking at what I did between leaving from work and going to sleep and deciding what mattered to me less than being a successful businessman. Bye, WoW, it was nice while it lasted.
