The hubscore and all of the other statistical information is derived somehow from how people interact with a hub. How long people spend on a hub is measured, the number of comments, the number of tags such as useful, funny, awesome, etc. these are all measured. Most of my hubs have an interaction rate of less then 10%. Is that good or bad. It seems kind of bad to me. I sometimes receive more traffic from outside sources then I do from hubpages. How do other writers feel about these issues?
