Thank you, Icv, AMFredenburg, and PhilAvent.
@Jackie Lynnley: Yes, the HP scoring system does discourage people from writing new Hubs, especially when high-traffic Hubs get low scores and that makes the Hubber score go down, too. But, management wants to keep it the way it is. If Google loves a Hub, you'd think HP would love that Hub, too! Looking at the overall picture, traffic to the site is considerably lower now than it was this time last year. Fortunately for writers, there are many places to post good content on the Internet.
