I’ve been trying to kick-start a community on a niche that I really enjoy - computer history with an emphasis on the people involved, computing culture, narratives and whimsy. It’s kind of hard to define concisely. It’s not news, it’s not retrocomputing, and it doesn’t have to be about really old stuff.
I don’t know if it’s a sustainable concept. I’m the only poster so far and I’m going to run out of bookmarks eventually. If you like this sort of thing, please jump in and contribute! We’ll see what interesting things we can dig up together.
