I think that in the future I should be more picky about the comments I upvote. At the same time I don't get that many comments so I used to upvote even comments with just thumbs up emoji/ single word. I hoped that those people would stick around and make higher quality comments in the future. But most of the time that did not happen.
it'll be easier to br pivky if you know that for instance 5% of your post rewards will go towards the comments you vote! will be an interesting experiment
