Just a few years ago, you would never see such a disparity in votes vs comments. But these days, this is pretty much the norm. I've seen posts with 10K+ upvotes and no more than 80 comments.
I'd say in about 2 years, the entire place is going to be bots with AI generated content that try to mimic "real users" using their new Dynamic Product Ads tool. Not sure how that's legal as I thought ads needed to be marked or differentiated from regular content, but here we are.
The future looks bleak and AI even bleaker. Because it's going to be used against us to make the rich richer and not to make our lives better.
I can echo the last part. I refuse to use the app so I use the both the website and mobile version. Both are almost unusable. Comments often fail to load, just showing the Reddit logo animation. It takes 8 reloads to sometimes load a reply to one of my comments. Half the time it never loads just stalls at 30% loading. The post options to attach images or media to a comment doesn’t work on mobile; tapping the buttons literally do nothing. It works on desktop.
