Only problem with algorithm is that it is prone to occasional slips where you open a random cat video (or any other bait) and your recommendations start showing that more often, you keep clicking those and before you know it your recommended feed is full of that.
But if you know how to tame the algorithm for only the content you are interested in, it is amazing. I like my twitter, youtube and insta recommendations and have discovered many new creators who I wouldn't have otherwise.
