This looks cool, but it was hard for me to figure out what it is. Hacking is an overloaded term, so I started off searching for things like MongoDB. Maybe on the homepage you could put some examples to provide context.<p>Just curious, where do you source your recipes from? Edit hah it looks like they're from MakeZine.<p>This is a cool idea, best of luck with it.
Two points from my very quick experience with the app:<p>1. You've spelled Haking/Hacking inconsistently between your logo and the title bar.<p>2. If the user performs a search with no search terms the server returns a 500 error.
