So I went onto Gmail to check for a message from someone

and wound up spending 1 1/2 hours going through the whole thing, about 2000 e-mails in my inbox, a bunch of spam, a lot of unread mail that needed to be categorised, etc.

But I now have a total of 3 e-mails in my inbox, and everything has been either deleted or marked read (even if I didn't actually read it, I can search for things to read later).

Whew!
