I generally don't care much about blogs that are gear reviews, or about specific techniques, or about somebody's photoshoots. This isn't to suggest that these are bad things, but merely that they're not interesting to me.
Some blogs I read pretty regularly, are:
Shifter. Daniel Milnor, the photographer at large for blurb.com, and his own take on the world of photography. This guy is an actual artist, no bullshit. Or at least minimal bullshit.
Idiotic Hat. Mike Chisholm's blog. I don't read it very often because I am find it appalling to be reminded that he's smarter, funnier, and a better artist than I am. I hate that.
Adam Marelli is an actual artist with his head screwed on very tightly. He knows what he's talking about, his posts and videos and whatnot are all spot on as near as I can tell. And he avoids pretty much all of the silliness that we run across in photographic pedagogy.
Of course, I read ToP and you should too.
Sound of a Shutter. mmaria writes pretty insightfully about photography from time to time, mixed in with some personal stuff, and an almost complete absence of boring technical stuff.
