On topic, stack overflow does exactly what the article is talking about; They lock down their sitemap and make special exceptions for the Google bot:
https://meta.stackexchange.com/a/98087
https://meta.stackexchange.com/questions/33965/how-does-stac...
I can understand SO's reasoning but it only perpetuates the incumbents' stranglehold on the internet.
I feel like I often see submissions which are, even tangentially, related to front page material rise very quickly.
Regardless, congrats to Knuckleheads Club for fighting the good fight.
Their robots.txt, on the other hand, is more restrictive of Googlebot:
https://stackoverflow.com/robots.txt
User-agent: Googlebot-Image
Disallow: /*/ivc/*
Disallow: /users/flair/
Disallow: /jobs/n/*
..Resubmitting interesting content that hasn't got traction earlier on is however explicitly allowed in the guidelines IIRC.
