I'm an irregular contributor to Wikipedia. I've written a number of short articles, expanded a few, and made lots of little tiny fixes. I often don't log in for the latter, so some of my edits (mixed in with some of my partner's) appear from 64.81.59.235 instead.
I've also dabbled in disambiguation link repair and fighting vandalism. Try it, they're fun.
Out in real life I'm a software engineer, working in the Amazon.com search group at A9.com (when you type something in a search box on amazon, that's our stuff at work). I once helped start a LUG, ran a BBS, use IRC, wrote drivers for MMC and ran out of TLAs before this sentence acquired humor value.
I have most of a degree in each of English and computer science, so I'm somewhat frequently involved in articles on those topics. But Wikipedia's a wonderful place for reading all sorts of stuff you didn't previously know was interesting, and I've edited some of that too, mostly for little things.
I write various free software packages, mostly small and simple ones, and work as a Debian developer.
My personal page, if you're into dull self-interested rambling, still more sentences written in the first person singular, or to see sort of what I look like.
Why 65535? Well Moppet was already taken, I've never liked accumulating long lists of aliases (actually, I never liked thinking them up, and never got past that to see how I liked it.) 65,535 is the largest value expressible with an unsigned 16-bit integer.
