I created this so users have more control. User has the ability to shape their own feed, by setting preferences to skew content by length, humor, more popular, show less seen content and they can view and adjust the current topics they are being shown. The post you see even tells you the reason it is being shown. A Boost feature allows you to boost others posts so more people see it, you will see that creator more. People who Boost also get a boost in their videos being shown to others.
