One of the main features of steemit is getting a monetary reward for people voting for your posts and you voting on peoples posts, which is an integral part of steemit however I don't think anyone but the poster should be able to see the amount of money they are making on a post until the initial one week payout is complete.
Why I think this:
There is no shame in the fact that we are all more likely to vote on a post doing well for a portion of the payout and I am a big fan of the voters getting rewarded for helping a post do well, however because people vote for the payout many people fall into the pattern of trying to get the largest return for their vote, which again is fair, but in the long run I think this will and already is negatively effecting the whole steemit ecosystem.
It means that people often don't vote content that they read and enjoy because they see that it doesn't look like the payout will be big. Which means that many new steemians posts won't get votes because of the payout.
Whereas if only the poster could see the payout during the initial week people would be more likely to just vote for content that they enjoy which would help the wider community as a whole.
When steemit grows and has a wider amount of active users I think this will most likely become less of an issue as the site will likely gain users that come purely for the content not to create content, however I think with the amount of users currently on the site a feature such as this could be beneficial to the overall growth of the site.
