My point was that the 'average' computer user is easily bewildered by many things, and using an IRC client isn't especially difficult compared to them. Using a link to a ready-made config for a web IRC client is easy and relatively painless and doesn't require any additional magical insight and fairy dust by a group of Silicon Valley dreamers. The use cases for Slack is arguable an Euler diagram circle exactly on top of those for IRC, a slightly different one than those for FB Messenger or Skype. Slack is redundant/bloated because of IRC, Messenger isn't.
