We’re using Slack intensively this semester, and while keeping teams up-to-date and communicating is always good, I have to admit that I’m not yet clear on why it’s become so popular. I’m hoping that experienced Slack users can set me straight: what are some valuable features I should be aware of? What is Slack good at that other forms of online communication aren’t? The value of intra-team communication is undeniable, but thus far Slack doesn’t feel like it’s enormously better than other solutions.
