The user's age on HN is in the ballpark of 25-40 years old, as it's a tech website.
The website in OP is a meme generator, and I'm sure the ballpack would be 12-18 years.
Now considering this, I agree with alkonaut.
Oh no, I'm aging out, I'm 41.
I'm curious why you put 40 as the top end there. If I were going to guess at an age range for this site I go lower and much higher.
I imagine he meant in the normal distribution sense, where 25-40 comprises ~70% of the userbase; entirely anecdotal but I get the feeling that's a reasonable assessment.
Honestly, though, there are some corners of real life (especially in those early teen years as you allude to, but even among full grown adults that should know better) where you will find people with this sort of personality. These type of reactions are not surprising in that context. Social media does seem to do something to amplify raw vulgarity and classless behavior though.
Exactly the target audience when we are discussing <topic> in tech, isn't it?
Edit: I misread / didn't read. My broader point is there is a lot of talk about how bad tech is, and yet here we are on a very technical and at the same time reasonably civil forum.
HN has users well outside that range though, it is probably under-represented on the lower end and I would suspect over-represented on the higher end based on my IRL interactions with a fairly large number of HN'ers.
