This account is 52 days old, but the user behind this has been reading and posting on HN for a bit longer (let's say since PG decided to put HN online).
For the other comment, my point is that "genuinely wise" is much rarer nowadays, and instead we're drowning in "genuinely clueless". This is why you shouldn't learn about something's worth by reading HN comments nowadays. Instead you can put a limited amount of time actually studying the subject and then decide if it's worthy of more of your time or not.
