Perhaps? I'm looking for systems that attempt to address such perceived advantages. Perhaps this example is clearer: A system where user reputation tapers off over time. This would impact the early adopter advantage. This would probably be a bad idea for many online communities but perhaps not all. In general I'm interested in any system that has a different model then the traditional vanilla up button / like accumulative system.
