Earlier this month Food TV nerdling Alton Brown quit Twitter in a huff, leaving it to the "sick, low life scumbags" (some troll was impersonating his wife). In a blog post this morning he announced his return, crediting "nice, normal folks" and a "real live celebrity" for nagging him to get back on. "This time though, things will be different," writes Brown. "Although I'll tweet as regularly as possible, I'm only going to answer questions twice a week." But watch out people, he's "loaded for troll."
