Dan Seeger is a vagabond misanthrope whose capability to socialize with other human beings diminishes greatly without the sturdy foundation of a weighty topic such as a carefully considered debate over which Replacements album is the best or which season of “Buffy” should have served as the end of the show. He once spent an entire day watching Michael Bay movies as a form of masochistic penance, but he’s never going to watch Billy Madison, no matter how much you beg. He tweets and blogs, but still fearfully refers to smartphones as “robots.”
