This is really cool: Journalism student Mike Kielty has set up a blog devoted wholly to Sketches by Boz. He visits places mentioned in the essays, photographs them, and writes about how they've changed since Dickens's time. The blog is here, and an article with some background information is here. (Be aware that there's a rather racy ad on the left side of the page, those of you who like to be warned about these things in advance.)
Kielty says he doesn't plan to continue his blog longer than a few months, but here's hoping he enjoys his time in the Dickensblogging community, however long it lasts!
