Perhaps I'm a bit spoiled, by following lots of great bloggers who place more importance on their readers than their advertisers, but are the most popular photography blogs, to quote the podfather Adam Curry, "NACAR" blogging?
Some sites seem to be more ads than content. As for useful content? That's maybe a sentence or two. So, how is it that photography blog readers have put up with this for so long?
Just remember, with so many advertisers to please, the amount of honest writing that's possible continues to shrink.
Forget about possible even, there's no real incentive for honesty. If everything is great, anything can be sold.
