|laziness, impatience, and hubris|
I actually specifically chose/designed my handle a long time ago to be as useful as possible while still reflecting some small spark of personality.
My given name is Gregory, and I when asked if I prefer Greg or Gregory I usually - just to be a pain - say 'Gregor'. Though my mother never called me by that variant. (Dad has started to recently ;-} )
The 42 is a reference to the Hitchiker's Guide to the Galaxy ..ahem...trilogy...
And the point is that I use the same handle on ever site I go to - and usually find it wide open. Furthermore I acquired www.gregor42.com and use email@example.com so as to make me easily accessible to anyone willing to look.
Of course, now that I've ranted about this I'm forced to think of a Dennis Hopper quote from the film Search & Destroy : "Just because it happened to you, doesn't mean it's interesting."
Wait! This isn't a Parachute, this is a Backpack!
