Dtube appears to be still a promise but there is a huge contendor... YouTube. Technical issues, year on the market and the staff is behind Youtube is not easy to surpass. Google is the owner of YoTube. I would think Dtube will be an alternative to YouTube and, in order to grow, it will need followers, lots of traffic, money and it would be only bringing advertisers which come from a huge audience. Time would tell. For the time being, push Dtube to everyone you know.
