I’m probably not the first one to do this – I wrote some CSS that hides all instances of popularity (i.e. karma and comment counts) on lobste.rs, HN, and old.reddit. What motivated this? It was my tendency to ignore possibly-bespoke submissions simply because they had less than X points.
Hiding karma might not be for everyone, but I’d encourage giving it a go and seeing how your behavior changes. Here’s how front page looks for me: https://i.imgur.com/16PPCvs.png
I named this user style after the beauty-recognition-disabling tech from a Ted Chiang story:
"Think of calliagnosia as a kind of assisted maturity. It lets you do what you should: ignore the surface, so you can look deeper." - from the short story "Liking What You See", by Ted Chiang
Currently I load the CSS at document-start using Greasemonkey on Firefox, though pasting it on any user-CSS browser extension would do (like Stylish, Styler, etc).
