You left out one.

The Dudley Do Righteous.

She is a combination of diplomat (after years of raising children, and trying to keep them from killing each other, she has become rather adept at keeping the peace..or so she THINKS...) She TRIES to branch out and claim a new identity for herself but quickly finds that she is only comfortable doing what she has always done...
Coffee Klatcher: She has her coffee sitting next to her as she types her Pithy Phrases hoping that everyone is online so she doesn't have to wait too long for a response...because she is on a roll. She has everyones' best interests at heart...and is definitely not an effective debater and worn down very quickly... She just enjoys the comraderie...she realizes that her opinion will not change anything, so she tries to engage everyone by using Eagle Scout tactics...and truly enjoys observing all the reponses and interaction it invokes.

She is, by far, more interested in the people than the issues at hand.

She is a legend in her own mind.
