Open Source DIY
I hate DIY.
No, really: I really, really hate DIY. So the idea of a site devoted to the damn subject is pretty appalling. Except that Instructables has a clever twist (otherwise I wouldn't be writing about it): this is a kind of collaborative, open source DIY, where people share their DIY ideas, tips and secrets, and others make suggestions for improvement or just generally comment on things.
It's a nice idea. But a better one would be where somebody else came around to your house and did it for you. Now that's what I call real collaborative DIY. (Via TechCrunch.)
