Oh the positive attributes, hmm. I like this question. I just started talking my hubs seriously, and decided to get involved with the community. I find there are genuine people who are willing to offer advice, and encouragement. I am now starting to follow people who inspire me by their hubs. Hubpages itself offers a lot of tutorials, which are important to me, plus I have found info on how to make money on You Tube.
I purposely avoid any negative forums that are speaking about points going down etc. I just stay focus on the positive. I have noticed my writing is getting better, but not sure if that is related to Hubpage. com, or just me constantly writing. Richard Bach, author of Illusions and Jonathan Livingston Seagull, once mentioned in an interview, you have to just keep writing, and you will improvement.
