I've often remarked that the most productive use of a blogger's time would be to simply to point a camera out the window wherever they were.
I don't think newscasts should have hosts. They should have a camera and point it toward things. I don't think newspapers should quote anyone. They should print the text of proposed legislation, not talk about it.
I found the video fascinating, and well-done. I didn't know much about Barcelona, at least not up-to-date knowledge of it. I recognized lots of buildings in it because I'm not illiterate, but I've never been there. It's vanishingly unlikely I'll ever go there. Still, it's useful to know what it's like there, even superficially. You can find out all sorts of things by paying attention. There was a street sign pointing out the way to Karl Marx Place, for instance. That was interesting to me, and told me things. I didn't notice a sign for Hitler Circle, or the Stalin Memorial Abattoir, or the Mengele Park Towers, or Vlad the Impaler Children's Hospital, or the Idi Amin Culinary Academy, but they might have been there, and I missed it. I'll have to watch it again.
