I agree that most people don't care, and probably don't have the energy and time to care, and that's mostly fine. That is, until Google decides to arbitrarily close their account, with no recourse. Sure, over the number of people who use GMail, only a tiny percentage experience this, but it still sucks. And in that case people are usually more upset that they've lost their photos, docs, etc. than their email.

I don't really see an actual problem here, unlike some others commenting, but it is a general shame to me that more people don't have their own email domain. It would make the world more... colorful... somehow, even if in just a small way.
