@sir I was asking myself yesterday why I prefer Telegram to IRC. The big things that put me (as a tech-savvy person who like federated things) off IRC are awkward sign-up and auth (/msg NickServ isn't a pleasant experience), and having to be always connected to get a scroll back of messages you missed, or notified if someone pings you.
If those things put me off, I bet there's a dozen others that stop it proliferating to the mass market.
