I like it. Having a username with a meaning would definitely feel more signifcant. I often use a user name given to use as an undergrad at a university (not here though) The only significance mine has is it reminds me of a time when my eating disorder was at its worse. I should change those too, but then I constantly forget them. Probably not the safest things, but my passwords are all cryptic and not easy to guess (I use a password random generator). Also, though it is out there in places, my mother's maiden name (often asked for password help) is not at all easy.
