An anonymous reader noted a story discussing the aftermath of the Wikipedia fundraiser
and says "The writer suggests that Wikipedia can earn $50-100 million a month by a simple text ad. He also suggests that contributors should be financially rewarded and that the lack of financial reward is the reason why 98.3% of registered Wikipedia users are inactive.
What do you think? Should Wikimedia Foundation put ads on Wikipedia? Should contributors be financially rewarded? What compensation structure would be best?"
Personally I think the independence of Wikipedia is great, and any advertising would not only compromise that integrity, but give contributors a sense of entitlement that the site is better off without.
