I don't care what berniesanders say's however it is very difficult for me to upload videos on there, I don't have a camera and so i use my phone and the process of uploading a video on there is constant trial and error. There are bugs and errors that pop up when i'm trying to upload, then if those are fixed the videos come out upside down or the wrong rotation.
If Dtube can fix these issue's then the Alexa rankings will fix themselves, if not then it isn't worth it to be using Dtube.
