Thanks for the feedback.
Short term the features upon release will be your bread and butter for creating and answer questions, but moving past the initial release there's a lot of ideas to tackle some of the problems previous sites saw.
One thing I'm keen to tackle and keep in mind is that delegation and the ability curate with a massive vote doesn't make a site on Hive (or previously Steem) and isn't the way a site such as Quello will become a staple. I think there has been a lot of blame on this in the past as a reason for either lack of adoption or retention when instead it's covering up a bigger issue.
I think there will be problems to solve, but one thing I've learned during my time on Steem is that the feedback from the community is always awesome and through enough iteration, we'll be able to iron out any kinks that come our way.
