Please don't do that. I like the fact the IRC is controllable in plain text via commands. Also, what is wrong with knowing about servers and ports? Why is it that IRC should be changed to appeal to the masses?
Everything IRC.com is working on usability-wise is happening on top of the existing protocol. If you're an advanced user you'll be able to connect to the server with your IRC client of choice just like you always have to any other IRC server.
Nobody is going to stop you from just using the “old” protocols. Maybe it’s even backwards compatible in the way that right now you can also add port 80 to a URL but you don’t have to.
Now everyone including grandmothers knows what a pen drive is.
And people are using a chat application 99% of the time. Anything they need to know to chat with their friends, they will learn, fast.
IRC did not die because it used ports and servers. That actually had nothing to do with its decline.
IRC was replaced by something without the feudal structure of founders, SOps, and Ops, and the medieval control they had over normal users, muting and kicking people off channels all the time.
It was a social issue, not a technical one.
And at the rate things are going, that percentage is only going to be going up. We're tunneling more and more over HTTP(S) -- lately, DNS over HTTPS has been unleashed upon humanity --, so ports as a concept are kind of an endangered species at this point.
