Yes! I've toyed with the idea of building exactly this (except I'd do it for Facebook and Instagram, too) for around a year. I didn't really have time to devote to it though, so I've just kind of ended up not using social media anymore.

Part of me relishes that I no longer have that distraction, but another part of me feels guilty for eliminating that personal cost at the expense of reduced interaction with loved ones. (Our personal relationships have been co-opted for ad revenue -- what a time to be alive.)

I would love to just get an email once a week with a digest of stuff I've configured it to care about.
