While Hubber Score is seen as a bad way of judging Hubbers (especially new writers who might be dismissed for this), it's still a good thing to increase. Whenever I reach 100 I like to stay there to show that I'm dedicated to making quality Hubs. And the higher my Hubscore, the more I learn from my articles and what examples of a good hub are for future reference.
Sadly the system is broken beyond belief. You can post multiple insightful comments and have many upvotes on your articles, but your Hubscore won't change. But stay logged out of the site for several days, and it shoots up. There is zero consistency with the current scoring system so it's hard to tell what you're doing right or wrong, and some may rush to amend it, when they are in fact doing the opposite of what they want to.
It shouldn't be scrapped, just fixed. If it were more consistent with rising and descending scores, I think it would give us more incentive to keep those numbers up. I don't really care about Hubber Score any more because it fails to go below 98 nowadays.
