The various Ubuntu Q&A websites have an unique and very fresh way of doing things. The voting, badging and reputation system is well thought out and the moderators work well with the community, keeping us under check!
To start with I found that scores and badges were of great interest, but then I went through a stage of getting embraced if the last few points are corrections to others questions. Now I realise that if the editing have made the question readable, understandable and means that it gets an answer, the reputation points are well deserved. The feeling of pride when your first answer gets you 15 points is brilliant and quite inspiring.
The answers to questions on the whole, are mostly positive, with a few answers that need ignoring.
My question, as there is supposed to be one, was it a group or an individual which came up with the concept of the way the community works?
