If you actually joined the website 13 days ago though, I'm not sure if you are really in a position to evaluate the shift in culture over years timespan?
I'm not talking down, in fact I think it is likely they have either been lurking for much longer than they've had an account or this is not their first account. That's the case for me, for instance.
There's no higher "status" or anything to be gained on how long you spend on this silly site, I just think it is relevant to the specific conversation.
