Sure, sounds great; except what's to differentiate it from the actual sites like Lifehacker, Zen Habits et al? Aren't these links aggregated by even other social news websites such as Reddit (or dare I say Digg)?

Don't get me wrong, I'll hear you out and I'm certainly interested, but it's hard to get excited about "let's re-create xyz" posts. What makes this idea unique?

Sounds like this would be better as a stack exchange mini-site? I went there and didn't see any lifehack, diy, etc.
