No, Valve didn't put out another video, nor am I actually a robot. I just picked up this screen name ages ago for the Bob and George forums (BnG was a megaman sprite comic) and have been using it since.
But! As I'd like to help make this con happen, I guess I should introduce myself. At Everfree 2012 I was the guy, often at the writing panels, with the blinky box containing a Rainbow Dash... and the guy that stood up in the comedy segment at the closing ceremonies.
I live in Seattle, in the Ballard area, where I work at a small engineering company, doing the intellectual scut work, so the engineers can get the credit (and any blame). Honestly, I love the job; I do most of the designing of control panels, and the result of most of that work is cleaner water. I could go on, but that would delay the PONY! part of this intro.
I am the author of the fic-in-progress, Equestria Trek, a shameless Star Trek/FiM crossover. I've got some other writing I'd like to do, but if you just want a glimpse into my (often MLP related) madness, check out my tumblr.
As for what I'm looking forward to with EFNW2013? Well, I hope to have my first long-form fiction story completed, and the blinking box upgraded (and possibly repainted). I'm also thinking of doing some Cosplay, if I can find a suitable character I could pass as (I'm not shaving my mustache, but I might dye it, so maybe Steven Magnet). I'm also looking forward to putting more faces to screen-names; in the dealer room I picked up a flyer for Ponymush which is becoming my new primary online hangout.
Anyway, hello!
