Build an API that can convert a twitter username OR Google+ username OR Linkedin ID to an email address. It won't be 100% accurate, but if you can have 20% accuracy, there are lots of people who would pay for such a service.
If you don't want to go that route, then go buy an establish website from Flippa, use your coding skills to auto-generate unique pages to rank in Google (content farm), then flip it months later for a profit. Keep doing this. How to auto-generate unique pages? One idea is to deep crawl old forums, and get an unique sentence and do an exact match search in Google to see if it's in the index, if not - assume that content is unique. Or go ping random blogs that aren't popular in Wordpress every second, scrape their content and put it up so Google sees it first. Black-hat, totally lame, but you just want make money, and I'm your son :)
