I used to always set up and run my own mail servers. I no longer do so, not because I'm lazy, but because I have better things to do with my time than be a sys-admin, and worry about downtime, logs, security, and backups.

Sure, Google has your mail. So use multiple accounts and keep your really private communications somewhere else, or use S/MIME or PGP Mail.

But who the hell cares about them having data for an account that is mostly subscribed to public mailing lists?
