I really like the writing in the intro, but having "Horrible Search (of Slack)" as the first item in the justification for the entire product is a really bad idea and seriously weakens the argument. The trouble is that, even though you may be able to point to ways it could be better, in absolute terms it is incredibly useful. The last two companies I've worked at use Slack, so what I'm saying is based on something like 8 years of daily experience. Searching internal company Slack history is a fantastically effective way to retrieve information about other people who have confronted a problem similar to that which you are confronting today. Yes, I absolutely agree that they're black holes in the sense that information that could go on the permanent public record is available only to a few, and then lost forever. But the problem there isn't search, so search shouldn't be the first item in your product manifesto.
