I neither own nor operate bash.org. I wrote the scripts, collected the seed content, initially in quotes.txt, and operated at geekissues.org/quotes/ until its move to bash.org. AMA
It's funny that this should come up on the frontpage today, because just yesterday, I chose to go and find and install ircN, which still works just fine, by the way.
That is how I collected the quotes originally, by using ircN's quote commands, which saved them in a file called quotes.txt, IIRC.
Then, I would occasionally entertain the channel with random quotes.
Eventually, I converted quotes.txt to quotes.html and posted it on my website.
Then I built a PHP+MySQL database with a submission form, then some basic anti-abuse and moderation features.
Yes, I still love and use IRC, and I just recently installed mIRC and then ircN, and aside from nostalgic value, it's still great for conversation. irssi is my go-to client in general.
