I agree with the thought that the magazines (the pay-for content) should focus on D&D and get back up to the quantity of content we've seen in the past, as well as increase the overall quality. If they get back to what we, as readers, would like, then a GW article in the mags would be welcome. Until then, I'm happy to see at least some support being provided in the free content section of the website.
It's worth noting that the magazines underwent a change in leadership and direction mid-year 2010. The new editor, Steve Winter, has been quite forthcoming with his interests, expectations, etc. and has posted editorials and blog posts about how to submit for the mags, citing what WotC is looking for as the mags move forward.
There's been some hubbub about how things haven't really changed much (and some say the quality has decreased) in this time, but keep in mind that content for the magazines is plotted out many months in advance of an issue. It takes time to invoke changes, approve proposals, get them written and turned in, order art/cartography, format and typeset, etc. I have something in the pipe that, by the time it is published in early 2011, will have been in the pipe for over a year.
All of that said, I'm interested in hearing what people think of the article itself. The Wizards Community has thus far been pretty quiet on this article.
So, chime in. Let me know what you think.
