Thanks. Yes I agree about having non-bot minnows build a reputation with commenting! I actually wrote a similar proposal a couple months back The important thing is for the community to recognize non-generic & relevant comments and reward people. It's hard for bots to create non-generic replies or at least it will take a lot of work to have bots pass the Turing test. The community will have to be diligent to determine which comments are relevant, but I think that'll make for a good system.
