You would be hard pressed to find anybody using IRC who doesn't also use email and wikis. Once you add IRC to your toolbelt, those things, as if by magic, stop appearing to be the best tool for every job. Actually, it works that way with most tools I find.

But that's the appeal of IRC, the protocol is simple and it's easy to write tools that plugin and work with the stream.

In the case of links, a little bit of Python and the phenny framework let me write a bot that scraped links and post them to a private Twitter feed. That's a lot more flexible than a wiki for my purposes.
