It's been a while since I've contributed to Stack Overflow and I wasn't planning on writing this. I guess it's a sign of how broken this feature is that I'm here. You see, I'm deep down a rabbit hole where I find myself trying to rebuild my blog and it's so slow. So I did some searching and to came to a Stack Overflow answer that seemed promising. Here are the comments:

I wasn't reading super carefully just yet and I saw "a year ago" kinda out of the corner of my eye. So I got excited that the answer would work for me too! After a few minutes poking around my config file and the Jekyll documentation, I discovered that the problem was fixed in 2019. Therefore that answer was outdated "over a year ago".
Could I have seen the hover text? Not a chance. I've had years to learn to do this and it's just not happening. Could I have seen the date on the answer? Sure! But having (what looked like) recent comments saying the answer worked seemed like this was a perennially useful answer. You don't have to look far to see example. The very next answer was the one I've started using.^[The --limit_posts 1 option, not --incremental, which is still unacceptably slow for a REPL.]
No problem, I thought, I'll just leave a comment explaining that the answer is outdated. You can clearly see that comment right here:

I'm just baffled that this comment UI still exists. It makes comments take up more space on the page, which indicates they are more important than answers. It deliberately hides useful metadata about the comments. Nothing has been done to prevent trivial comments from hiding useful comments. What are we doing here?
