There's still a decent size contingent of non-technical people that look at exampleapp.com the way I'd look at wellsfargo-online-banking.com. I don't blame them: subdomains imply authority. While I'm sure there's more, github.io, herokuapp and GAE/Appspot are the only services I know of following this practice, and they cater to a developer-level technical audience with the assumption that they'll work out a better name.
