If I've learned to rely on something, it's this community providing references to amazing and relevant material. Thank you so much.

Aside: As it turns out, the Whuffie, especially its weighted variety, is very close to what I had in mind for a distributed cloud architecture I am working on. I called the concept 'community currency' but the monetary reference always puts people off. Perhaps referring to Whuffie (or the related Kudos) will help better communicate. Again, many thanks.
