Bash.org has been up and down quite a few times for the past few years, there's only one real reason that it's interesting and that's for it sentimental value. Who ever browses bash.org for new content anymore? IRC's only used for open source communication and general knowledge channels nowadays anyway, not much fun going on still.

Unless general IRC channels and networks experience a revival there won't ever be a better source for IRC quotes than the internet archive's mirror of bash.org.
