I think it could end up helping a bit in the short term. But in the end an even more complicated system (even if in principle better) will reward those spending time gaming it even more.

The system ends up promoting an even more conservative culture. What might start great will end up with groups and institutions being even more protective of 'their truths' to avoid getting tainted.

Don't think there's any system which can avoid these sort of things, people were talking about this before WW1, globalisation just put it in overdrive.
