As this could probably be perceived as a thread hijack, I apologize. And I probably should refrain, as I fully expect you to ignore what I’m about to say.
Yes, I think 65 is very low, especially for the number of hubs you have. And yes, this is probably why your hubber score is not higher. I paged thru your titles, and am pretty stunned at the rate you’re turning out hubs. If you’re making loads of money, then carry on. If you’re not (and given your preoccupation with scores and accolades), then I would say this…
Stop writing and start reading. Do this for at least a month. Write one or two hubs a week if you must.
Read the HubPages help files, view their videos, tutorials, etc. Read loads of “How to Hub” hubs, but by reputable hubbers. Lots of what you read may go over your head, but keep reading, then re-read. In my bookmarks, sunforged, relache, Mark Knowles, Lissie, and darkside have their own folders. You could also read any “how to” hubs written by HubPages staff. Read about traffic, tags, keywords, titles, SEO, etc.
Search the files for HubPages contests, and read winning hubs. A high hubscore and hubber score does not always mean the hub is top quality. You’d definitely be safe reading habee’s hubs as representative of good quality. See if you can pick up any tips to make your hubs better.
Then before you start back into mass production of hubs, spend some time making your current hubs better.
