I use it in a very limited capacity of keeping in touch with people I knew in the 90s on IRC. But I drop out of doing even that every now and then when I need to focus on other things, because IRC tends to be a drag on my productivity sometimes.

I also try to sit in freenode channels that intersect my interests, but I'm not anywhere near as active in them as I was back in the day. But that's where all the good developer-related channels are now.
