It's always fun to see ideas evolve over time. Heather Wood Ion and I wrote a paper Towards a model of Micro Philanthropy as part of a workshop on Complexity and Philanthropy I held at the Santa Fe Institute with Murray Gell-Mann in May, 2002 (pictured at left). Six years later, the Telegraph in UK recently quoted me on the subject in an article, Ole Gunnar Solksjaer's charity donation: Broke? You can still be a philanthropist Micro Philanthropy has hit Wikipedia, so I guess that makes it real. Peter Dietz and others have picked up on the idea through Social Action Network, too.
