I stand by what I’ve said about this in prior discussions:
I’ve yet to see a large scale reputation system, on the internet or elsewhere, that successfully incentivises healthy community dynamics – which is probably why they always face ridicule in pop entertainment.
More often than not such systems only help to amplify innate human flaws, such as us/them thinking.
The fact that our badge system could still use some improvements is not a good reason to implement a new system with a very bad track record. I tend to agree with you when it comes to our “First X” badges. I’ve always been of the opinion that Discourse should focus much more on human-awarded badges rather than algorithmic ones.
