My story is similar to Suaveant's, to a point...
I started online in about '92; I was already out of school a few years and had a job in D.C. where I had a loaner laptop with a modem and decided to try it out.
I got into the fido net and a couple of local BBS's (TIDMADT, CrunchLand, Bubbles) and I was poking at things Pagan and such and didnt want to be identified IRL (I worked for the Guv'mint).
So, when asked for a username, I casted about for a bit, and finally settled on the long version of my name:
the short form of which is spanish for 'a little bit' and is also the name of my miniature dachshund, Murphy's Poquito.
IRL my name is Dean Murphy, and you can see one of the other connections to my online name by rotating the long version above 180 deg.
BBS'ing and now Internetting is a kind of 'telepresence' experience for me, and I only expect it to get more and more that way (Esp when Geek Code C++++). And thats the rest of the name.
