A lot of poor quality content and same content talking about Steem's future bla bla bla (nothing against it, just get's boring imo). Also noticed a lot of creators try to kiss-ass for up-votes (expect too much).
Most important, the mobile load times are basically non-existent. I would actually spend more time on @dtube if I can load videos properly, I give up after two videos don't load and move on to Youtube.
Obviously, it's a new platform and hopefully with time we can solve these issues.
