This is the million dollar question. I think the goal of "anonymity for most intents and purposes" is worthy, it's been how I've enjoyed HN and Reddit, but I also know that it was just a matter of time before stylometry and other meta-analysis of post history become 10 second tools for everyone. Now the cat is out of the box.

I've been thinking about this a bit, and I've landed in that having a stable identifier across ALL comments & posts is a poor default. We still probably want some coherence, at minimum within a thread, eg to follow a back-and-forth. The site itself may also use stable identifier for abuse prevention. But there's no reason one should have the same username externally traceable for posts about completely different topics.

In practice, this could be done with low friction pseudonym creation, which all ties to the same account privately.
