Photoblogging is yet another way to introduce a lot of data flow to the web. As regular text blogging requires minimum language skills, photoblogging requires a camera and basic photography skills. Talant is nice to have, but way too few people actually do. I don’t think that my photography skills are up to the level to maintain a photo blog, but a text editor I can handle.
Meanwhile, I do enjoy ocassional photoblogs, like this one.
