It seems to create affinity scores based on which videos you complete watching, like or share. Then they also maintain similar affinity scores for every tag on those videos and the creators of those videos. So as you watch stuff, you feed becomes tuned to your preferences without needing an explicit 'follow' step.

Users have little control of what videos they see explicitly, but if you like 5 videos with the same tag, it will present more videos with that tag.
