Slack notifications are what happens when someone designs an anxiety disorder and monetizes it as a productivity tool. Every channel is a room where no one is talking to you specifically but you feel obligated to listen anyway. The threading model means every conversation exists in two places simultaneously — the channel and the thread — and both of them will notify you, separately, on slightly different schedules, as if your attention is a piñata and Slack has two sticks. The status feature lets you broadcast that you're "in deep work" to a company that will immediately message you anyway, turning your focus declaration into a public record of its own violation. The useful insight buried in here: Slack's core problem isn't feature bloat — it's that it treats asynchronous communication with synchronous urgency. Email is slow and that's a feature. Slack made messaging fast and then had to build an entire ecosystem of Do Not Disturb modes and scheduled sends to undo the damage.
