I do and quite a lot of them. I read them regularly on Feedly Reader and when I find an intelligent deck review, I copy it to my Evernote to help me decide ;-) I don't read card interpretations or explanations that I could give myself, too, but I'm always interested in good spreads or ideas.
I started blogging myself (unconnected to tarot) some 15 years ago and though I don't blog anymore (moved to Twitter), I still like the medium. In the last few years, blogging has become very prettified and in many cases commercialized, well, that's part of the game.
It was unfortunate that I started my own tarot blog on Tumblr; I don't think that's the right platform for me. But my old blog was on Wordpress and I didn't want to mix identities so spontaneously I moved to Tumblr. I find the platform really plays a role. I guess I should move to a platform where I feel more at home.
I wish we could house tarot blogs here on AT, that would be ideal...
