I have both Matrix and Revolt, but they remain empty unfortunately. The advertised public servers are so full I usually leave within an hour. And I can't get my friends to join my Matrix channel instead of the discord server they are used to using. I also fully admit that real time chatting is just not my thing, so my bias is definitely towards non-real-time social media sites. Growing up with dyslexia and AIM, I'd always feel really insecure about spelling things correctly and it always takes me a while to send a message. Again, fully a me-issue that other people generally don't have, but I can dream haha
Every day I relearn that Neocities still exists I'm surprised. I also had no idea it was open source! Thanks for the info! I honestly love the "small web", and neocities really has a large portion of those kind of sites. I also follow some Bear Blogs, though I think it's rare to find comment sections on these sites, so communication is limited to emailing if this was to be considered social media. But it definitely makes me feel more cozy than any of the corporate owned media sites.
