It’s funny because everyone shits on tiktok for it’s short videos yet I regularly watch videos that are 3-5 minutes long if not longer.
Your feed shows you what you interact with. Outside of ads I rarely see content that’s not related to my interests and most of the videos I see are much longer than a vine.
Which is especially ironic to me how vines weren’t considered attention span killing brain rot that everyone sees tiktok to be.
