I don’t know what Cohost was but I’m pessimistic about Lemmy these days. Note that the link is to an article moaning about the centralization of sites like Reddit and that Cohost (whatever that was) failed because it was run by the same type of people. At first I didn’t click on the link because it says “audio” so I expected it to be audio and I didn’t feel like listening to one. It’s a written article though.
There is a famous Erik Naggum rant about XML at, no wait, I better not link it but you can find it with a search engine if you want, which means you don’t get to complain to me about it since you are the one who went looking for it. Very NSFW and VERY politically incorrect. Naggum died in 2009 but anyone who published a thing like that today would be raked over the coals.
