I try to login with GitHub and get an "Incorrect login" window. It works after I confirm my email, however.<p>Anyway, this may be good, but the interface is kinda heavy, don't you think? Also, it seems that the "blueprints" should be written in JSON or whatever, something a programmer must write. If you're not offering flashy interfaces with click buttons and you only want programmers, perhaps you should just offer a CLI interface.
