Comment (by cypherpunks):

 The suggestion that *I* should use Snowflake entirely misses the point
 here: I'm trying to get Tor to make *all* users more uniform, so that we
 all have an anonymity set to blend in to! How many Snowflake users do you
 think there are in my city? I would guess that there are not a lot. Also,
 from reading #21312, it doesn't sound like Snowflake is quite production-
 ready anyway.
