We just ran across this unusual, in our considerable online travels, calculator trying to help determine the value of time and money invested by nonprofits in social networking. It is a little complicated for our tastes, thinking about recurring end user nonprofit individuals and actually deploying practical, enduring tools and solutions, but we praise the Care2 nonprofit online specialty social network for their uncommon efforts (especially for nonprofits) to monetize data and time (and necessarily, mindshare) invested.
