I agree with you totally. It use to drive me up a wall to see my score go up and down daily. But not as much as my actual hub scores! Soon I realized not to be too concerned with my score. That it would fluctuate all the time. As long as my score didn't drop by 20 or more points. I received great information through Answers and Questions. I received these useful tips!
1) You should read and comment on other hubs;
2) Follow those hubs you have an interest in;
3) Ask lots of questions;
4) Visit your Forums;
5) And hop some Hubs (this really helps out a lot);
6) Link your hubpages to other sites
Always remember to go to the Learning Center to find out as much information as you can. Read, read, read! And post, post, post quality hubs frequently.
