My hub scores and hubber score have actually come up. Once upon a time I was a 97, but then for unknown mysterious reasons it dropped and leveled out at 91 with occasional hikes up to 94, and then back down.
My hub scores were all fairly low until last week. Once upon a time several were at 100.
The last few days when everyone was talking about their dropping hub scores mine actually came up. Some came up 10 or more points! The overall average of all hubs came up by 10 points.
While everyone was complaining that their hub scores dropped several points when they tweaked their hubs, mine went up several points when I updated mine. I don't tweak mine and never have. If I find additional new info that would make a good addition I update it, photos, as well, etc., but otherwise I depend on other people to let me know if there are issues with spelling, etc.
The downer IMO is the drop in income. Income is what matters, not hub or hubber scores. Google doesn't know or care about our internal scores, followers, comments, etc.
Google cares about writing quality and comprehensiveness. Google likes long articles that include as much as possible of what a person is looking for so that they don't have to go shopping all over the net trying to find all the info they want and put it together themselves.
Google doesn't like parts 1, 2, and 3, etc. because that means the customer won't find everything they want/need to know in one place. They have to go to a lot of other sites to find what they're looking for.
I find that people on here are judging hub length by their own needs. What most people on here need is a short article they can scan quickly, write a quick comment, and then move on to the next article and do the same thing. Long articles like mine, most likely get pretty tedious to hubbers that just want to get it over with. So they write their own articles short and make several parts in different publishings to meet their own and other hubbers needs.
On the other hand, people who are genuinely looking for particular information want to find that info and learn what they need to know. They would rather find it all in one place than have to hunt and hunt all over the web trying to find it, or jump to one article after another. We are supposed to be trying to please Google customers' needs, not our own.
Expect my scores will drop into the basement again soon, but it's nice having them up a bit while it lasts.
