I heard [0] for a long time it was all about long form posts to a massive number of Google Groups mailing lists with custom tooling to manage subscriptions (bc the Groups UI is poor). I understand these lists range from general to hyper specific.
But then I’ve also heard much of the communication has shifted to Slack or other tools. Slack tends to degrade into chaos at a certain size, and at Stripe’s scale I’m curious if this is a big pain point or how you mitigate it.
