It was a collection of silly quotes from IRC channels everywhere, many of which dated back to the 90s. It was rarely ever updated in the 2010s, but now, the URL no longer resolves.
Last capture was July 2023. https://web.archive.org/web/20230601000000*/bash.org
EDIT Someone archived all the quotes on the Internet Archive.
I have used both, aside from the monetisation (Nitro), Discord (and Slack) has a lot more functionality. Not sure it’s ‘correct’ to say that people are stupid because they prefer a 21st century version of IRC.
Matrix stack would be the 21st century equivalent. Discord is just another Skype - entirely a proprietary product that you don’t operate yourself. Fine for corporate use where people don’t care about longevity because it’s not their problem or interest, but trash for everything else.
