Earlier quoted context omitted.
IRC is not going anywhere but projects like neovim use gitter primarily while IRC is linked using a bot. They view the IRC chat in gitter. Dunno if Gitter is better than IRC as I have only used for help and support (for me) but Gitter was far easier to use than IRC. Just Login and start chatting. I don't think IRC is going anywhere either... We just have alternatives to freenode now in Gitter
Apropos, does anyone know of a hosting provider with one-click installs of Weechat? It would be nice to have something slightly more self-hosted than irccloud to recommend to the GsoC/GCI students who keep disconnecting from freenode :) (You'd think with all the Wordpress one-click-installs that this would exists, but I can't find any yet at least.)
