It’s definitely a pro-social, social platform. It shows that you don’t have to rely on polarizing or adversarial content to drive engagement (_
cough, like Facebook & Twitter cough)
Eh, it still exists. I have gotten in a few cohorts that were quite toxic, especially near the election. There's still quite a lot of vaccine/mask vs anti-vaccine/mask content, and you general political crap. It's easy to get off of those, the dislike button is definitely your friend, but if you don't have the willpower and self-control I do think you can fall into the same rabbit holes as Youtube or any other platform.
Remember that the platforms we complain about also started off totally fine, but eventually greed caught up with all of them.
