We are going to make the ability to see who liked your comic more visible for the creators to monitor in the future. Right now, all forward facing statistics i.e. likes, and shares are kept relatively hidden due to privacy concerns as we don't want to discourage anyone from taking those actions.
As @jelw mentioned prior, there are a lot of readers and creators who feel uncomfortable with certain aspects of sharing being visible.
The aforementioned ability to see who liked your comic being more visible will live on the new creator dashboard that is being built. We would also like to integrate better statistics regarding where your comic is shared (i.e. if an episode has 7 shares, then we would be able to showcase how many were on Facebook, Tumblr, Twitter, etc).
Currently, the Facebook api that we're using to count the share function doesn't only track the number of shares directly from the episode page but also track the number of times it's re-shared on Facebook internally. There are other technicalities with counting shares that we'll have to work out before fully integrating this feature for creators, I hope you understand - we really want to build this out.
