Would you pay $5/yr for HN?
alexandros: [Since I can't update the post itself anymore, I'll write an update with a reply]After the great discussion that has followed, a number of good modifications has been proposed that could significantly reduce grievances. The fee could be one-time, and proceeds donated to charity. Also, uers with a lot of karma could invite other users (in case they cannot register due to no cc/no paypal/underage etc.) This would probably require an area for users to request invites etc. but even the process would certainly make users more mindful of their posting. Additionally, the new users could be mentored by the one inducting them, further increasing culture preservation. Keep the thoughts coming.
