Straw man. I wasn't comparing slack's feature set to BBM, just refuting the point that before Slack, barely any businesses used group messaging. > Pre-slack virtually no businesses used realtime group chat. BBM, Real time group messaging, used by businesses. It was popular long before group messaging was popular. Yes blackberry is now a joke, but there was a time when many businesses provided employees BB for communication, and it's users loved BBM. ... That comment also missed the point: Slack didn't enter a new market (the claim from the referenced article), it entered a market that already was saturated, and by having a better product, is winning in that market. Hipchat, Campfire, Lync, et al, are all competing for the same customers that Slack competes for. Whether slack is better for businesses, or whether it was a direct competitor to BBM, completely misses the point.
