Motivation for Facebook or Google: maximum time on website. The most profitable reputation engine is one that feeds the user his or her own preferences back to them (Judging by my news feed Yahoo is doing this). This is exactly how Fox News or Huff Post works except that instead of self-selecting news that supports my worldview it is being done without any internal processing. You might could get away with expert truthfulness on some issues. However, the scariest thing for me is that things that are opposing opinions will have an assigned truth value and the best metric would be popular opinion.
