I can respect not wanting to have constant meta-discussions about each submission, but I think SEO is an interesting topic in its own right. Especially the sneaky-but-still-white-hat type. I'm not even sure there's necessarily anything wrong with it; it's ultimately based on creating content that people want to read. (I didn't flag this article, for example. It's an interesting story.)

But I think it's worthwhile to note that this post was almost surely written with the primary intent of boosting page rank as a sort of guerilla SEO.
