My opinion Dtube forward will be the main choice, Dtube gives more than others. This is just the early stage of development but progress is very rapid. Video quality is getting better and better. It's just a matter of time, but I do not think it's too long to get ahead. The important thing we should be able to produce quality video not just to get upvote. And we must also provide objective comments for constructive criticism. In the future maybe Ftube will increase its tags. We'll find anything we need on Dtube. Let's develop the Dtube together.
