If you are given an opportunity to become the admin on musing.io,what is that thing you would want to change or develop?

I think that there will end up being a lot of repeat questions.

I would suggest reserving a small proportion of the musing Steem Power to reward the admin team for removing / redirecting repeat questions to previously asked similar questions. Stackoverflow has this kind of approach.

This will help ensure that there is one source of answers for each question. Over time musing will then become a useful reference tool for people to seek out answers to common questions as well a place to ask new questions.
