Link bait article about link baiting
Okay, so I realize how gullible I have to be in order to link to an article about link baiting that's pure link bait, but he's followed his advice so well, and it's all so well written, that I can't help it.
In much the same way that understanding propaganda helps you both manipulate other people and avoid being manipulated, this article is a good read precisely because it helps you learn what people are doing (very successfully) to make you do stuff.
Keep this in mind next time you're thinking about "voting up" an article designed specifically to attract attention. In other words, do what I say, not what I do :)
