tuukkah has provided an index of IRC channels he is logging in both HTML and Turtle RDF, and the nice thing is that SIOC is being used as one of the representation formats. For example, here is the #sioc channel from today in both HTML and Turtle. Logs of #swig are also available.
The script is written in Haskell and is available here.

Tuukkah, great work on SIOC-ifying the IRC logs!
And it’s good to have public logs of #sioc, both in RDF and in text form.
