It's genuinely so fucking weird to me. Out of everything, why did Harry Potter gain this kind of stubborn hold on pop culture? I read through the series in the second grade and largely forgot about it until I met a girl who was completely fucking obsessed with it. Had little scarves and jackets and posters of it, just Harry Potter shit. I thought it was so weird until I started working and realized there were grown women in their 30s and 40s and beyond who were still fucking obsessed with Harry Potter. Bizarre.
Harry Potter allowed people to build the first online communities. It's not like they didn't exist before, but it happend during a time when the internet became more and more available to people with simpler ways to interact. I mentioned Usenet above, and I'm sure most people don't know what that is, but they do know what message boards are.
on top of that, HP appeals to people's sense of tribalism: you are sorted into a House full with people like you while you compete with other houses, this in a time when kids have been told everybody is the same, everybody should be accepted and everybody's a winner. It appeals to something they were denied while growing up but was very important.
