This is a most excellent place for technology news and articles.
Uber was originally marketed as ride-sharing, too. Just an app to find people going the same way. Of course, I'm fairly sure that their current iterations was the plan all along as anyone with enough business sense to start those companies must have predicted that there would be people who take on Uber/AirBnB as a primary source of income. But sharing your house or planning a shared trip is much more palatable than "Landlords but Worse".
