Twitter is reportedly looking into implementing an “undo” button, but reports suggest that it might be hidden behind a subscription layer. Is that a useful feature? Can twitter survive without paying customers, and if not, what kinds of features would you want to see in a “paid” Twitter subscription?

Meanwhile in the social media world, Facebook subsidiary is finally facing down its Instagram problem — well, specifically the one where loads of under-13s are on the platform in defiance of the account rules — by proposing a “my first Instagram” tailored for the kids.
Is that a good idea? How can Instagram keep kids safe online through machine learning alone, and what age is the “right” one to allow your kids onto social media anyway? It’s a tricky problem.
