One thing I've noticed lately in keeping up with all the major players in Internet marketing is that once they've surpassed a certain level of authority among the thirsty public, they stop pumping out quality content and start generating catchier but less informative articles. Much in the fashion of news reporters who focus mainly on the stories that grab people's attention, these bloggers seem to throw tips & tricks out to their public to keep them interested.
I think what people are really afraid of is that they'll miss the next big thing. Sure, once in a while, good ol' Shoe comes out with a very handy post. After all, I am of no mind to make enemies with the guy but come on. But after a while, there's only so much you can learn about affiliate marketing from some show, book, etc. It seems as though they're just repeating the same thing in different ways, like the SAT test does to test your mental agility. Not to mention, they like to do a lot of product pushing posts (especially Chow), but I suppose that comes with the power.
Of course, who am I to argue with their witty contributions? After all, they have thousands of readers and ultimately, that's what matters most. All I can hope is that at some point they start giving back to their loyal readers what they're really hungry for-- good information. Information that will keep them ahead of the pack.
That's just my take though.
