So far, the only possible downside I can see is that maybe it creates a semi-addictive chasing of sats on the platform, but that also is non-unique to stacker news as a social media platform, and the micropayment cost of doing anything makes you think a bit more, making a counterbalance to social media's addictive nature. So really, it has problems, but they are less severe than what you find on other platforms. Maybe I'm missing something though
