I'm trying to use DTube (as a consumer), but it still has one downside that's really hard to overcome.
Often I find a video I want to watch, and start watching it, then it just stops playing. I really want to watch it so I leave the tab open for a few hours, and it still doesn't load. I try it next day, and still stops at the same point in video.
Maybe more IPFS nodes will solve this, I'm not sure... but we definitely need to solve it before DTube can be usable for masses.
