I don't think it's a good idea to assume / hope that HN remains that way. Money is still an aspect of the existence of HN. It exists because pg has enough money to run it, and its existence aligns with his current desires. This community could just as easily dissappear in a way equivalent to what we're seeing with Twitter and Reddit, if pg wanted. And it could not be easily replaced, because its existence is dependent on pg's money...
