So, if a person's userid is 20 days old, then does it directly mean that the person has been using the site for only 20 days? what kind of logic is this?

Hence why I asked if they can pass adequate judgment on the matter, which I've now realized sounds horribly condescending.

Even so, I think the majority of frequent HN-readers (ie, those able of passing judgment on its trends) will have set-up an account, and I think the age of this account is a good indicator of how long you've spent reading it.
