1. id read tutorials or reviews. As for videos , it would probably be a lecture or debate of some kind, entertainment wise i enjoy music vids

2. I enjoy articles or posts that people can gain knowledge from, like scientific theories, programming tutorials etc. the subcategories leads to an abyss lol. I try to keep my stuff short and sweet without ommiting vital info
