How long did it take you to get ramen profitable?
idlewords: If you mean 'earns enough to cover monthly living expenses', about thirty months for the ad-supported bedbugregistry.com, and one week for pinboard.in (thanks to an enthusiastic plug from Daring Fireball which resulted in a large number of paid signups).My limited experience with project revenue is that it's quite spiky, so that you have to be earning considerably more than a minimal amount before you can have confidence that you'll be able to cover your bills in a given month.
