I miss IRC, for a lot of the same reasons the author misses Facebook. Being above 35 like the author, I think it’s more the fact that people just aren’t chatty anymore. It’s anecdotal of course, but if I look at myself, I’m really not that chatty anymore either. I too used to have late night chats about random stupid things, but right now, I can even remember when I last saw 3AM unless it was to feed a baby or clean up after a sick child.
So when I say I miss IRC, it’s probably more true to say that I miss the freedom that comes with having almost no responsibilities. Maybe I should work on making more of my time, mine though.
