For some reason I think this going to happen to HN too, and I feel it is at 3. And I'm not sure if I'm in group #1 or group #2.
Before what date do you think people can be group #1? Or are you ascribing the group number to contributions rather than date of joining?
So after a few months of lurking, I registered here, and now it's my daily[1] go-to site.

So there were the people who got here first, then the people who discovered the site in 2008, which was a long time ago, and have fair claim to being 'group 2'.
So I think 'Group 3' is me. A defining characteristic of 'Group 3' is that goes back to pre-Snowden times, before the truth was known. Kids today must be 'Group 4'.
