Once again, Joan Westenberg hits it out of the park with Why Personal Websites Matter More Than Ever:
I don’t know why we talk about walled gardens. That seems to imply something beautiful, something worth defending. It conjures images of beautifully maintained flowerbeds protected from the outside world. But that’s not what Facebook built, what Instagram built, what Twitter built. They built paved, unshaded, barren hellscapes, trapped us in them, and surrounded us with guard towers and razor wire, intended to keep us in, not protect us from anyone else. There's no "garden" here.
