The blog originated in January as a catch basin for mental detritus, for the kind of stuff not good enough for print, but too good to waste on casual conversation or, worse, mere thinking. But this spring I began allowing "comments," and the blog suddenly mutated. America, it turns out, is full of smart, clever, creative people who happen to have no interest in working and whose employers have unwisely given them Internet access. Thus every day, on my blog, these strangers show up, just to shoot the breeze, flirt, kvetch, veer off topic and, most of all, pay zero attention to what I have written.
