This is a thoughtful post.  I tend to agree with it, but most of the leaders are going to be developers.  Who knows what reasons they have for being anonymous.  We can't really expect them to put their identity out there for the world to screw with.  It would be nice if there was more upside for a person than downside, but just look at how a team of trolls appeared and spent all day (June 12th) attacking UF and NEM.  Now in the case of UF, he somewhat deserved it, but it isn't necessarily that smart to have your identity tied to a project.  NXT, BTC, PPC and others have all be quite successful with anonymous leaders/devs.
