There's a great blog post I saw today that happens to refer to my past piece, "'What's the ROI of Social Media?' is the Wrong Question."
Tom shares his own worthy perspective and then links to several resources either in favor of or supporting measuring ROI "of social media" in general, several who say it's not necessary or even impossible (where I stand with regard to a TOOL, yet ROI for an initiative can be), and a few in the "maybe" camp.
All the links he references (have looked at several so far) appear to be great reads (and I'm very honored to be included among them).
Where do you stand on the ROI discussion?
