What does Slack do well? Love using Slack to communicate with co-workers. We can make boards to help organize working groups. Slack keeps our work on track and gives us an outlet for personal interactions around the "water cooler."
What does Slack not do well? Nothing I can think of....Slack is top-notch.
What do you wish you had known about Slack before using? How easy it was to use and how quickly it streamlines one-on-one and group communications.
