First, I'd like to say that I really appreciate the basis of ranking people based on 'likes' and other performance based measure and I think a far better option than raw post counts. It enables well spoken, knowledgeable newbies to be quickly recognized for their contributions, and it's also a far better way of assessing the credibility of a poster. However, I had a thought on an extension of the current model, whereby 'likes' of high ranking members would contribute more to someones points, on the basis that quality recognizes quality. It's very similar to trust-based identity systems, whereby you decide to trust or reject an electronic signature based on their relationship with others. It may or may not fit in with the long-term plan, but was a thought that came to mind.
