I admit, Sven Goodsson's site - IMPROVE YOUR KARMA - is pretty darn good!  Not so much commenting about the content of the Karma dialog as the concept - what he's doing with getting people to participate in the dialog about creating good Karma.

You can add "Good Karma deeds" or "Bad Karma deeds" to your own personal version of Sven Goodsen.

You can use the "Karma Meter" to monitor you own reputation (or some else's) in MySpace (see above).  It's not a deep analysis - but it's a very intersting way of inviting people in and getting them engaged.  This is a well designed, well functioning site.

You can upload a photo of yourself - and I did - and it will analyze your "aura" but it did not show me my photo with the aura analyzed so I don't know how that would look - or how the site operates with the photos.  I suppose it will put it in a gallery view eventually -as they have with several other people who submitted their photos.

And when you "Spread the Message" it looks like it's a Cell Phone ad - so maybe the whole thing is a viral site that's designed by PR Agency … I don't know.  By buying a Motorola Red Motorazr V3m your "Improving Your Karma" by allowing Motorola to donate 17 dollars USD to the Global Fund to Fight AIDS, Tuberculosis and Malaria in Africa.

Seems to me Sven Goodsson's site - IMPROVE YOUR KARMA is one of the best I have seen to engage people and to do something good with your money.
