As HN becomes more popular this will become more prevalent. The same thing happened to Reddit over the past 14 years.
"Please don't post comments saying that HN is turning into Reddit. It's a semi-noob illusion, as old as the hills. "
The barrier to entry to HN is anyone with an internet connection and motivation to create an account with absolutely no verification. That’s quite the low bar and just invites bad behavior.
In many old forum days you had to be invited. Case in point- lobste.rs is invite only.
