I've gone by "Twylo" online (IRC, social networks, at work, etc...) for ages. I stole it from an episode of "The Dick Van Dyke Show", where Rob has a dream that an alien from the planet Twilo (who looks like Danny Thomas) has come to take over the Earth. I misspelled it completely by accident, but I like my spelling better.
