Yes, it's not new, & yes Uber is doing well in connecting supply & demand with a great UX.

For Uber to be worth its high hype & valuation, it's going to essentially expand these types non-employee situations. That's why I'm "mixed" feeling about this, as I like great UX, smooth marketplaces, & know many people who want part-time work, not full time.

But, I also know many folks who had "decent jobs" (nothing special, but they can raise a family) driving UPS trucks or other things like that.
