I don't know what curation trails are, but I do come to Dtube pretty often to check out videos, and there are some things that discourage staying for long. First, many times videos will just stall for a long time, so there are some issues with throughput that are a big negative. No sense staying and looking at a frozen screen. It seems like some videos do run good, but many don't. I get the feeling that there is some kind of throughput limits on less popular videos. There are a lot of awesome things about Dtube, but if the videos stall all the time, it will be a non-starter for drawing viewership.
