Positive social feedback is super useful in achieving goals.
Also, I totally agree that it's key to have a balanced and accurate sense of self. But the vast majority of people are affected by social feedback. c.f. this study at Wake forest University http://psp.sagepub.com/content/29/5/623.abstract.
Positive social feedback is useful, but I think that I would take issue with the definition of social here. Social means genuinely social, not a paid reproduction of social. I would think that people who would genuinely enjoy this service may have some self-image and narcissism issues which would be better served by spending the money addressing those.
This is the same kind of awesome as claiming to be an amazing Casanova due to having slept with many prostitutes. It's not always about the action, but the intention.
