Slack is good because it does one thing really well. That's organizing group chats amongst coworkers. That isn't monolithic, the FANG approach of having you enter their environment to use a single product like Hangout is monolithic. Rival services get in the way with this OS-styled approach, when really internet utilities should be following the same focus that unix did. Most people don't like to feel locked into one companies' suite of applications. This industry is far to complicated for that approach. That's also why Slack won't replace email. We already use email addresses as our internet mailbox, where all our accounts are linked. Email is the most professional way of electronically sending someone a message period. Slack may of gone public, but that seems to be far beyond their reach.
