I wouldn't necessarily agree with @trincowski that it is looked down on to share youtube links here

Well, maybe "looked down on to" is not as accurate as "not as well rewarded as using DTube".

A few other notes - dtube deletes your videos after a month or two.

I had no clue about this. Is that a recent process or have they always deleted old videos? Either way, no YouTuber will change over, if their videos are gone after a while. DTube must find a way to monetize things, so they can start paying for permanent storage.
