I take Uber or Lyft, whichever is cheapest. The ride "sharing" industry is a brilliant innovation, but I seriously doubt it can support Uber's valuation.
I personally don't want to have an identity on the web. If that's against the rules could you kindly point it out to me? That's definitely something I'd be interested in learning about.
It's not in the guidelines yet but it will make it in there eventually. In the meantime, it's against the rules in the sense that we don't allow it, and ban accounts that do it, for the reason I explained above.
