Voting functions completely differently between the two sites. I didn’t say that voting doesn’t matter, I said that no one cares about the “points.”

People can and do use voting to let others know about interesting content or to express displeasure at seeing a post (which is why it is sometimes surprising to see any downvotes on certain posts such as the nice one I was responding to in the screenshot).

What people don’t use them for is a measure of merit or reputation. Voting here functions much more like reddit used to years ago. It helps sort content by what people want to see.
