I recently listened to a few of @exyle's vlogs there to get some basic understanding of the latest Steem related drama, whilst doing other stuff. I do this with lots of youtube channels as well because.. of a constant need for distraction perhaps? And I can't read all the time.
Not sure it helps much but that's my limited perspective on this. I think the videos seems to buffer more reliably now than like six months ago when I last tried Dtube, so that's something!
