It was Douglas Adams (I think) who described a VCR as a machine to watch TV for you, so you didn't have to. It's good joke, but joking aside I've been thinking for some years now that it could apply to social media.

You could have your own AI bot that reads your newsfeeds for you and tells you only what you might be interested in. The AI is tuned to your own preferences, not the social media provider's.

Has anyone done anything like this already?
