I used to participate using a recognizable name for networking reasons. But I was self-censoring myself too much, since I don't agree with lots of HN's groupthink. So I switched to an anon handle.
Surely some level of self-censorship is desirable. If you disagree with something and doing it politely you generally won't get hit too hard from what I've seen (though I appreciate my account is fairly new).
Saying things like 'groupthink' are probably the sort of words you may actually want to self-censor.
