This website for sure! But also Neopets or Tumblr. Tumblr is more of 2010's and is a little more "endless feed", BUT it's got a lot of customization options and is very "nerd friendly" lol
Neocities has also been fun to play around with, but that one is like a brain workout lol, at least for me. I really have to work my brain to remember and relearn HTML for that haha.
Outside of technology, check out your local library and see what events they have. Idk what age group you are, but I know my library has TONS of analog-friendly teen events. Also any used game store, they usually have fun events there too
