This is a conscious duplicate :D
There are at least two more questions about it (The color of links in comments, On the current color scheme, and why it sucks - by the way, when trying to share them via the share button I discovered that by some reason both have the same url https://meta.mathoverflow.net/q/320/41291
) but I still decided to post yet another question about it since I could not figure out anything sensible from the existing ones.
So why are links in comments so hard to notice?
