The great promise of the web to let customers manage their own experience has only started to happen. But I saw a bright light emerge on Facebook. There are little "thumbs up", "thumbs down" symbols, as well as a "next ad" symbol under each right column advertisement. So you can start to influence what kind of advertising messages you see.
I love it. What a great idea!
I've written about customer managed relationships before. We are still a very long way from this ideal. But this is the kind of direction we need to see, and will see eventually.
