Hahaha this is true. It's really interesting seeing the creativity or background behind some usernames (and the randomness behind others haha). Sometimes it takes me a couple months to realise that a person I'm talking to who I thought I don't know is actually someone I do know, but under a different name. All part of the game I guess :P
I always love getting to hear the origin behind a username, and some have had the most random meanings that I never even knew it was the case. I love ones in particular that reflect one's interests since it defines the member so much.
I'm glad I recognize people more from their style of avatars/sigs than usernames. So it hardly ever confuses me... usually..
This is me as well, I tend to get adjusted to names fast so it's not hard for me.
