Teresa Nielsen Hayden, the Boing Boing comments moderator who posted Boing Boing's formal response to last month's Violet Blue "unpublishing" flamefest, is a smart lady who, judging from her own comments, doesn't afraid of anything. She invented the practice of removing the vowels from blog comments she deems out of line, to avoid scrubbing them completely from the public record. So I'm surprised to see that Hayden took down one of her own Twitter updates Monday, apparently because Blue linked to it. Teresa, wht th fck?
