People still fretting about "owning" their username on every instance.

@lmorchard How do they even handle multiples of a username? Still not totally understanding the distributed model.

@Jesse The first part (what most people think of as username) is unique per site, but no restrictions between sites.

Your "username" is not "Jesse" - it's [email protected] and that's unique across the web
