Yeah it's one of its problems. It creates a ton of shitty posts, not citing sources, not explaining standpoints ("threads" are horrible). It encourages low quality sensational posts. Or funny jokes. That's been my experience at least.
It also encourages you to be more concise, clear and mindful of what you want to say. The problem you outlined stems from the posters and not the platform.
That’s only useful if you have really simple thoughts with no nuance to express.
Yeah. I mean sure, you can have really deep thoughts, elegantly condensed into a couple of short sentences, but when you're eventually required to clarify something for one reason or another things are gonna get messy.
