For me, what worked best has been smaller sites/communities! Specifically art/roleplay spaces (with the caveat these spaces also have a lot of drama and people who live for said drama) and virtual pet sites somehow lol. But I also feel like people online just aren’t as interested in talking or having actual conversations as much as they used to, so it’s less about looking in specific places and more about just… Getting lucky and finding someone on your same wavelength I suppose.
Gaming can be another way to meet people too. Can’t speak from experience there, but my brother was super involved in the Hearts of Iron IV modding community for years and made friends through it!
I see that .it domain 👀 siete italiani? Regardless it looks like a fantastic project, kudos! Especially interested in the static site hosting since right now I use an American service (Porkbun) for my own site, $30/year for 1 gb which is enough for me, but if I could switch to a European host for a similar price I totally would!
