The Wonder wheel that was introduced in Google about a month ago is now on Youtube as well. The wonder wheel in Google is really a very useful tool for diversifying search results and getting more insights to the related content.
You just type any keyword into Youtube’s search box. Now click on the Wonder Wheel at the top right side. Now you’ll see a graphical blue wheel that will show some video suggestions related to your search. Now when you click any suggestion in the wonder wheel, the results will be shown alongside. You can click on the different nodes to get different results. Anyway the wonder wall in Youtube is much like that in Google.
