Also, do you think you or anyone else is going to have much trouble telling who baby_rutabega_spoon is when he talks about his bingo business or ruthless_carrot_fork when he gets exasperated about password hashing?

These are exceptions. I can bet that a vast majority of people here would not be able to tell even pg apart from other posters if it were not for his username.

Besides these exceptions are fine, the anonymization is not meant to target them, but rather generic blabber-mouths whose comments are floating up only because of the group upvoting.
