Scooped!
I actually hadn't worked on the app in several weeks. Still... rats. This is the first time I've been scooped in software creation. It's frighteningly close to what I had in mind, but I guess if you like both Wikis and Macs, many core design decisions are pretty obvious.
Well, in a way, it lets me start using my application right now, without even having to write it first. So that's pretty nice, I guess, cuz it's a great idea.
