Ask HN: Would you use slack if you started a new startup?
Hating on slack/always-on communication is a bit in-vogue these days. I've also seen an org suffer a bit from notification overload, but I don't know what the alternative is.
If you were starting a new venture from scratch today, would you use slack? At what headcount scale would you layer it in, if ever? If you wouldn't use slack, what would you do?
