Uh, IRC still exists. Not only that, but you can use IRC in the browser, on places like Freenode and Snoonet.
I'm currently on freenode #reprap right now, talking to 300 some different people. We're still doing exactly what you're nostalgic for. And, I've met a handful of them in person at 3d printing conventions. (Link: http://webchat.freenode.net/?channels=reprap to chat on IRC right now)
Just because shiny new thing's moved in, doesn't mean that the old thing still isn't in use!
I'm also the same nickname on freenode as I am here. And still cranky as ever!
