> Is IRC really so hard to use? Yes it is. I've successfully had the following classes of people use Slack (across 4 teams): * Wife (Engineering PhD) * Dentist * Martial Arts Instructor/Gym Owner * EVP of Engineering * Business Owner * Student Loan Coordinator No way I could get them all use IRC, and enjoy it. Also, Slack has much more capabilities than just a chat server. For me personally, the fact that you can easily upload documents directly and collect them in "channels" cuts down on the email volume I get. It also works pretty great on my desktop, browser, and my iPhone.
