Privacy is deeply valued in most digital currency communities.
As a newcomer to Steemit, one of the things that surprised me is that you can see how much STEEM any user on the platform has as well as every single transaction they've made by simply knowing their username and viewing their wallet. See my wallet here and see Steemit Co-founder and CTO Dan Larimer's wallet here.
Clearly that was a design choice made by the Steemit team. What are the benefits of such radical transparency, and do they outweigh the costs? The privacy implications are important here particularly from a security perspective -- hackers can easily identify high value targets on Steemit and I'm sure they will.
