From the Machine Age Productions website:
David lives in the part of the OC you’ll never see on television, with his lovely wife, two daughters, and more than enough electronic equipment for a family of his size, because the year 2000 let him down on that whole hovercar thing. He runs Machine Age Productions, an independent roleplaying game design company. Websters defines ‘independent’ as ‘the opposite of wealth’ (look it up), so he also freelance writes and edits in the roleplaying game and video game industries. He’s won awards for designing games, which he considers very cool. He also thinks Bruce Campbell is the greatest man that’s ever lived. So your mileage may vary.
His particular poison is down-to-earth socially-aware fiction and gritty horror, with a quiet love of cyberpunk and whatever catches his attention.
He hates writing biographical pieces about himself, and would likely describe himself as a egomaniacal jerk with socialist tendencies. Observant as he is, he’s probably right. On the other hand, bios allow him to speak in the third person, which is a definite guilty pleasure of his.
He’s done work with White Wolf Publishing, Catalyst Game Labs, Green Ronin Publishing, Paizo Publishing, Posthuman Studios, and a handful of other publishers. He’s also written for the massively multiplayer roleplaying game, “EVE Online.” You can find a more detailed resume here. His critically-acclaimed Design an RPG in an Hour panel has been featured in The Escapist and Kotaku.
You can find him in a number of places.
The first of which is his Twitter account, http://www.twitter.com/davidahilljr. He posts there frequently. He doesn’t recommend sending his Tweets to your phone.
Second is his Facebook, https://www.facebook.com/davidahilljr. It’s the least used of the three, but used none the less.
Okay. That was only two places. Sorry. I guess a third would be his Google Plus, which is very active. Too much so. https://plus.google.com/u/0/118365124365067663191/posts
