Idea for a website. If you’re a developer starting a new project it can be hard to know if you have a good idea or not. I had an idea for a website that would be a cross between Slashdot and AmIHotOrNot: OSXIdeas.com. People could post ideas for OS X software, and people could rate the ideas and discuss them.
Developers could then get feedback on their ideas before investing in them. Non-developers could post ideas for software they’d like to have and see if any developers go for it.
I probably won’t do this website—but if somebody else does, that would be cool. (I’d be willing to help, but I don’t have time to build it and run it all myself.)
