One aspect of Uber that I think is missed as key, is not necessarily sharing, they are offering an existing service, a taxi service. It was there before, you share a taxi, you don't own it. What they did here is to take a very old industry and, well, disrupt it. They make it look elegant (home page looks like a fashion site), easy to use, rating of drivers makes sure quality is high, and no need to tip is a big thing, I hate when taxi drivers complain that I only left 15% and not 20% as if it's mandatory. Uber make the Taxi service better, more modern, that's all, and it's good enough. The next Uber IMHO will do the same for another service, any other service, that things like getting your service provider's photo in advance, following their arrival on GPS, no need for cash or credit cards due to a one click payment, known and final quote and pricing, and ability to rate them without the need to answer a recorded phone call with 10 questions, will have value to customers. Any service that follows this, sharing drills or not, will have a good chance of making it big IMHO.
