A hot topic this week in the blogosphere started with Joi Ito blogging about whether he'd lost his edge, gotten boring, and was not blogging about anything vital anymore because he gets so attacked in comments for having any opinion about anything.
Has extending our audience freedom of speech started to silence bloggers? I wrote about it here in some detail.
Lisa Williams spoke about a blogger's code of ethics here in her great blog "Learning The Lessons of Nixon" (also a podcast recording from her talk at Harvard Berkman Center is available). I really liked her notion of "The Living Room Doctrine" about what's acceptable in the comments section of blogs—speech and behavior that's acceptable in her living room.
