> An engineer at Stripe told me about their careful balance of email, forums, and Slack. They recognize that Slack is not suitable for meaningful conversations, so they automatically delete chat messages older than a few weeks to discourage relying on it for long-term archival. In retrospectives, team members often reflect on whether they chose the right medium (email, chat, or forum) for various conversations. This is bad news for Slack's freemium economics. I'm going to recommend we don't upgrade with this in mind.
