I understand the desire to be anonymous. If it's any consolation though, many users (myself included) have their website and resume listed right in their bio and don't mind other HN readers popping by for a sniff. From my perspective, nothing you wrote seemed even the least bit incriminating, if anything, it just showed you're probably a high performer who knows their worth in the market.

Anyway, no pressure to reveal yourself any more than you'd prefer, just my own thoughts.
