I must say, it's delightful to see this on the front page of HN.
A lot of people have been following indieweb POSSE principles for almost 15 years: publishing on their own site and syndicating elsewhere. I built my own platform for it that I used for 11 years, but you can use just about anything.
What's superb about the indieweb principles is that they're as simple as the web itself. It's worth digging into microformats, webmention, micropub, and the other lightweight standards the community has nurtured. It's all really good work that will become even more useful as more people turn away from centralized social media and AI-saturated services towards human websites. The indieweb is a slow burn but a really vibrant, growing, human community.
