I'll give it a shot again this year.
I was in the running to be a judge last year, but was not selected (I got nine votes, though).
I have been playing D&D since 1980. I've also played many other games over the years, and I'm familiar with many others. During that time, I also have been a subscriber to Dragon magazine, and at times other gaming-related magazines, so I've always stayed up on the gaming industry, latest trends, new products, etc.
I've been a member of these boards for more than a year -- since the old incarnation. I come here mainly to keep informed about new products and new trends in the gaming industry, but I do occassionally offer advice or my opinion on various subjects.
I graduated from college with a bachelor's degree; my major was journalism with a minor in English literature. I have been working in the newspaper industry since 1983, first as a reporter, then starting in 1986 as an editor. I write, edit, and do layout on a daily basis, as my job. I also write reviews -- albums, plays, movies, books -- so I know how look at something with a critical eye, take it apart, discuss its good points and bad points, and make a recommendation on it.
I know what to look for in published material -- grammar, writing style, strong art, use of visuals, layout, presentation. I have been a DM or game ref for most of my time as a gamer. I write some of my own material, and I use some published materials. I know what makes a good adventure, or good sourcebook, and what doesn't. I don't make a lot of money, so I've learned to evaluate gaming material with a keen eye toward value, and what can easily be used by a player or ref, and what will require lots of work on the user's part.
The judging period falls during a time when my job load lessens, so I can devote the appropriate amount of time to evaluate the products.
