@cwebber @mcc Scaling is hard and if you don't aggressively use a core feature when developing a system it's really easy to find it falls over hard, so I have some technical sympathy for BlueSky here.
I'm not in any way surprised, mind. I also fully expect to find that the end result is Bridgy Fed gets shut off basically forever "while BlueSky works out some scaling issues" that never actually get fixed.
