Yes, I think that a point or reputation system would greatly improve the quality of posts on Musing.io. I have seen some pretty shallow questions on here, not saying there are any stupid questions but a lot of these can be found with a quick google search. And if you are using musing , then I assume you know what google is for those types of questions.

I believe by having a reputation or point system. People will be able to see what types of users have genuinely good posts and will follow their example. Not only will it benefit the community as a whole, but people will have to do their own research in order to answer things and maybe gain a little knowledge of their own. So yes, it would be a good idea.
