I do agree with this. And I would rather see dozens of posts make tens and hundreds of dollars than any posts make thousands upon thousands.
But -- I think the concern is that once you've made thousands you're always going to make thousands. And the rep score adds to this -- if you post and you have a rep of 8, you're going to have dozens of upvotes before your post is even read.
I take a close look at anyone 6 and up. But maybe I'm biased. ;-)
I do too -- can't lie. But how many great posts by 1's are we missing?
I'd like to see the score once I choose to open a post -- as opposed to when I am browsing the listings.
