Ben from Kaggle. Open up the ~50 different individual datasets linked in separate tabs, and then quickly flip through all of them trying to get a sense of what each one is. That experience will demonstrate one of the main challenges we're aiming to solve by making Kaggle Datasets your default place to publish data online ( https://www.kaggle.com/datasets )
I've heard that Kaggle data sets encourage people to do "supervised" ML only. Is that true?
There's some supervised ML use of those, and a lot more open-ended exploration, visualization, cleaning, clustering, language modeling, etc.
