I tend to look on the bright side, so in that one the only thing I would love to see now is new ways to sort out content (similar to algorithms that promote quality content vs not quality content) and what we need is encouragement or rewarding quality over quantity, sadly hive has a weakspot on that one but lets see what we can come up with.
I would like a better filter or sort on content. At the moment with the weak reputation system it is hard for such things but some clever algo work could probably be done to serve up a user more targetted content. Then again that takes you down the rabbit hole of controlling what is being seen!
Hopefully it is all to come!
