Perhaps the author of the POM wouldn't like that
Sometimes, people intentionally make their post on Greenchip rather than the free pages because they only want their post to be read by Greenchippers.
If Stanford adopted your policy of showing the POM on the free page, then the fairest thing would be for him to first have go get permission from the author of the POM. Because the author of the POM changes every month, then some months the author would say "OK", and other months the author would say "no way," and the inconsistancy from month to month would be more frustrating to the non-Greenchip readers of the free pages.
Alternatively, if Stanford adopted a policy that the only posts considered for POM would be post by authors who agreed to have their Greenchip post shown on the free pages, then the quality of the POM's would decrease; and if Stanford adopted a policy that Greenchip posts would automaticly be shown on the free pages if they won POM, then the quality of ALL Greenchip posts would decrease.
The current POM system ain't broke, and doesn't need to be fixed.
Disclaimer: I do not work for, nor do I have any financial interest in Pi Yee Press. My comments are based on the fact that I currently get much more than $3.13 worth of value per month out of my Greenchip subscription, and I'd like for it to stay that way.
