Well that's a feature that alot of people would actually like to see and I'm sure if you went over to the musing discord server and made a suggestion. The thing is that I'm not entirely sure that's a good idea. Unless you're new to steemit then you'll know that there was actually a time when people could actually see how many people had actually viewed their posts.
The thing was that each time you refresh the page, it would appear as if another person had viewed your post. It was also gathered that alot of people don't actually read posts before they're voted, you just end up seeing lots of votes but not a corresponding number of views.
Eventually the feature was removed, whether or not it was because of the refreshing problem or something else is beyond me. Now the thing is that at this point in time, it wouldn't be wise for musing to do that because musing doesn't yet have the kind of attention that it needs to draw in alot of viewers, alot of People are actually just here for the upvotes.
It would be counter productive for them to display how many people have viewed an answer if only the people that answered it and the person that votes it are what appear as the total number of people that viewed it, because as a question and answer site, alot of people are meant to look for answers to questions on your site and although musing is growing at an exponential rate, it's SEO isn't quite there just yet.
If I'm being honest, I don't see this feature coming in anytime soon, but I could be wrong and if you feel it should be there then taking it up with the good folks that run musing would be a good idea.
I hope this helps.
There is not an exact answer to your question, as things like these are not discussed openly but there's a high probability that features like these will be added.
The creator of Musing is really looking forward to improve the overall SEO of the website, which will result in more people from outside world will join the application. Although, he can earn some more money through advertisements.
If advertisements are added then I am sure that these features will be added. It's all a speculation for now but I really think in near future!
