You can fail to maintain a wiki written in any software. The value of Confluence is when everyone uses it, so there’s one place to find info to answer questions like “why the hell did we do it this way?”

Nah. The prime use case of Confluence is to tick "yes I've written the documentation".

I love confluence because it has the worst search engine I've ever used. I used to think TikTok search was the worst: no matter what you typed, you would get only videos of people dancing. World's largest rock? Here's 12 videos of people dancing the renegade. 2020 election? Here's a video of someone dressed like Donald Trump dancing the renegade. Gatorade? Surely you meant the renegade, right? Here's some videos of people dancing the renegade.

But TikTok actually fixed that, so now Confluence is back on top. Good on you, Atlassian.
