My username on HN is not tied to my personal identity. The difference is I can jettison this persona, and all comments associated with it, at a moment's notice.

My username on HN is not tied to my personal identity. The difference is I can jettison this persona, and all comments associated with it, at a moment's notice. It is difficult to do the same with my real identity. That's what I mean when I say anonymity comes with the promise of zero responsibility.
