My first column for Game Developer Magazine came out some time ago; they haven't updated their website so I never got around to mentioning it. However, I do now because I've just submitted the first draft of my third column. I also haven't yet been paid for the first. I'd been saving this post for "hey, I got paid for writing something for the first time in my life", but I'm tired of waiting. (Also, technically, my salaried positions have required a certain amount of writing, so it's not quite the same achievement it could be.)
I will be posting the articles on my website three months after their publication date (this being the nature of my contractual agreement).
