The article was great from 10,000 feet. However, I think a beginner could get a little distracted with all the grammatical errors presented on the site. I feel these same errors may cause the article to lose some credibility.
Aside from that though, I think the graphics were well placed, and the links to other topics was very helpful as a refresher.
Technically, I thought the article was general enough for a beginner, and a good refresher for the novice.
