Tyler Cowen mentioned to day that of all the blogs he's seen, there's one that he finds "truly obnoxious":
I find the content obnoxious and I find the style obnoxious and I find the blogger obnoxious. By the way, I don't think it is a blog which has ever said anything negative about me.
His post was quite vague, and has generated a lot of guesses.
I can think of two blogs that I visit pretty regularly that I find to be quite obnoxious. One for the types of advertising used, and the other for its habit of trying to trick the reader into clicking on meaningless internal links that just create more page views. Any blogs out there that you find truly obnoxious, but regularly visit anyway?
