That proves Slack doesn't work in the same sense that it proves frictionless professional interaction doesn't work. As in, it proves nothing except it's an ineffective product for what humans use it for. Same as we'd say if Slack wasn't around -- "is IRC really the best way for us to do this?" No. Of course not. We don't live in a best-case world, however; the relevant question to their user base is "are we helping you more than alternatives?", and for an entrepreneurial community like HN, "what does the better solution that solves the same problem look like?"
