I think there's an important lesson here that you can take home right now: If your primary email is an @gmail.com address, you have your head firmly in the lion's mouth. You can backup your data. You can have fallback tools and services. You cannot backup your identity. And if that identity is controlled by Google, you are tying your online existence for the duration to the foibles of a publically traded company with…
This is probably a little hyperbolic. I have a gmail address and I don't expect it to disappear. If it does, however, I will still survive (after going through some temporary pain).
