I like IRC and use it. I have zero understanding why anyone on HN thinks IRC is a viable chat option outside uber-nerds.

Show me a training plan (outline is fine), case study or blog or anything outlining how to train my 50 non-technical coworkers in the use of IRC. They need image support and audio chat and all the other modern chat features users demand. Keep in mind there are a lot of chat options and users will walk if what you want to use is rejected by them.

IRC is not and has not been a even remotely viable option for anyone but nerds and hobbyists for many years now. i would be very happy to see any evidence to the contrary.

I mean, Discord is basically re-skinned IRC, and tons of "normal" people who have never heard of IRC use it every day.
