The few times I tried it it gave me loads of crappy content. No thank you, I'm not in for another doom scrolling addiction. The world has already enough addictive dopamine-f**ing time-sucker almost contentless social medias. I don't have the energies to fight against or maniacally curate my feed for yet another one.
I'd evaluate the usefulness of a social media or any other app by looking at a couple of metrics: 1) how much time do you spend there daily? 2) after you have used it, do you feel a better/improved person? I'd be curious to see numbers for these metrics. If anybody has links to papers/surveys that study how good or bad is a certain social media, please feel free to share.
If the positive comments are made in good faith, I see no reason to downvote/flag them.
