Matt Web has some thoughts on RSS which perfectly mirror my own:
It would be a good thing if RSS were more popular. When RSS is popular, it shifts the balance of power away from the social media platforms, which means that it doesn’t feed their ad targeting engines, or move people towards extremism. Plus it’s a less hectic, more egalitarian way to read.
BUT, the user experience around RSS has some sharp edges, and there are missing pieces that mean that RSS is unlikely to return to the mainstream. A corporate-owned platform could fix these missing pieces; it’s harder for RSS with its decentralised model.
I believe my app Feeeds could solve every problem with RSS Matt mentions: onboarding, newsletters, monetization, and discovery. And tons more. And it could do so without changing any of the infrastructure around RSS, nor force any required adoption of the app. Feeeds would be a voluntary tool, never requiring any site owner to change either code or design of their own websites. It's a community hub one opts into.
