I stopped using IRC several years ago. There are so many features in a multi-person chat that's lagging behind.

Jabbr (http://www.jabbr.net) is a good replacement for IRC, with features such as offline history, and embedded content (for code snippets, etc.)

URL doesn't work. Also I consider IRC's decentralized nature to be superior, just as it's simple protocol and established communities.
