You can still find those communities, but you have to go looking for them. Between about 2006 and 2012 I used to spend a ton of time in the Amiga community. It was an interesting mix of experiences, each of the different forums had their own feel and different core users, though there was a lot of cross-pollination between them, with discussions often a mix of underdog us-against-the-world wide-eyed optimism, nostalgia, caustic technical posturing and kitchen sink dramas. It was varied enough to keep my interest, but small enough to get to know the people involved (I recognise some people who post in HN who I knew from my Amiga days). I also learnt a bunch, first exposure to FPGAs was through Amiga developments, for example. If you're interested in classic computing I'm sure it'll still be relatively active, would start lurking at amigaworld.net and see where it takes you. I'm also sure you could find other similar communities if Amigas weren't your thing.
