There are many different motivations for people posting content online. Some may blog to get recognition, others may do it simply as an outlet to write what's on their mind.
Personally I'd argue that the very likes and comments you point to are what's most wrong with social media. When people are incentivized to chase engagement they'll post more often and post more extreme content.
IMO blogging into the void seems much less likely to lead to morale or anxiety issues than being in a bubble of people all trying to say whatever gets more engagement.
I think we likely both agree that the comments and upvote/downvote system here is used differently than Twitter.
For one thing, individual comments aren't algorithmically fed to us on the home page. For another, discussions here most often are just that, discussions. Assuming that my distaste for Twitter style likes/shares/comments and the culture built around it means I also dislike discussions is quite a leap.
