My Hubber Score went down - right after I have been super active too!
I know a lot of people say there is no rhyme or reason for the way the Hubber Score is generated, but I do know that the more active I am, the higher my score goes.
The other day I had an amazing day - I acquired a great many new followers, I was commenting all over the place, participating in the forums, asking questions and even published a Hub! To my dismay, my Hubber Score went down to 93 from a 96!
I like the scores, it gives me inspiration and a goal, so it's disheartening when I have an awesome day that gives me a lesser score!
