I haven't written any articles myself (way too busy), but I've greatly enjoyed reading some that others have posted.
A few are too subjective and not fact-based enough, but the majority are great.
I agree with article notations (and I saw that thread, but didn't have any real input to add so I didn't comment).
I might get burned at the stake for saying this, but I would recommend adding another ad right here to help support the site, since articles are so vertical anyway. Just as long as it's one additional ad, not twenty. I don't want ads to fill up the entire vertical space, but a second one wouldn't degrade the page experience to me, and if it gets you guys 30-40% more revenue per article and isn't intrusive, that'd be great.
Also, the social buttons at the bottom of the page needs to be bigger. Right now they are about 16x16, but they should be 24x24 or maybe even 32x32. Note: I'm not talking about a site-wide increase! The social buttons are currently the right size for forum threads and the rest of the site! But for articles, larger share buttons would be appropriate. [example]
At the bottom of certain articles, it'd be nice to have a link that says something like, "Have programming questions? Ask for help on [the forums]!", to redirect traffic back to the forums. The link should go to the correct subforum. "Have art questions unrelated to this article? Our [Visual Arts subforum] can answer them!". "Recruiting for a team? Post in our [classifieds]!", "Looking for a job in the industry? Check out the [Breaking In subforum]!"
