As good and cheap as Open Source apps are, they're cryptic. What happens if you have a really good application that is so cryptic that its success and longevity is threatened? The software needs a code bounty. For select applications, companies are offering code bounties. If you round out the documentation for a product, you can get rewarded with cash. The dollar values range from $300 to $4500+.
So, if you can write and dissect an application for the purpose of description, make like Boba Fett and hunt for that bounty!
