I don't know about the Dtube but i know that it's value will always be lower as compare to youtube.The Dtube server is very slow as compare to youtube. And the youtube is second most viewed website in the word, so it will take more time and will difficult for Dtube to replace youtube. Bye the way the post was impressive and unique i like it.
