Paul Tilley, the ad exec who killed himself because blogs were mean to him (or something), continues to inspire the most self-righteous and least self-aware of scribes to put quill to parchment, adjust their oft-dropped monocles, and write, more in sadness than in anger ("I think I'm more saddened than pissed off"), strongly worded letters to whom it may concern regarding those mean, mean bloggers. Today, Bob Garfield, who blogs at Ad Age, helpfully explains "the difference between commentary and vandalism." "Commentary" is when smart, mustachioed professionals who've written books and things blog. "Vandalism" is when people are mean to those people, on the internet. [AdAge, UnRelated]
