You might have been wondering what I meant when I suggested California Closets revamp my FB account-- my strange need to classify my social graph for optimal predictive ability (e.g. product and music selections). What would new ways to organize and search my FB account really look like? Do I really want a metric next to each friend telling me how similar our tastes are or how good of friends we *really* are?
As I was thinking about this, I was reminded of Xobni and its impact on the lives of two of the more addicted emailers I know. I remembered a former colleague telling me she found out I was her top emailee, but lowest emailer; she quickly stopped emailing me so much. Not only was the app cool, but useful.
Another friend told me Xobni clued them in to their "real" workgroup-- not the one the org chart dictated, but the colleagues who actually facilitate getting work done. Earlier today, someone mentioned an Adium app that analyzes IM usage stats to give you a sense of contacts' likelihood to respond, given your interaction history. Naturally, armed with this type of info, you can see how metrics can directly impact behavior.
So I started thinking about metrics in the hands of users (full disclosure: a discussion that evolved in talking to others). People always think of metrics as managerial tools, but really they should be in the hands of users to bring about the awareness and subsequent change in behavior that managers are most likely interested in in the first place.
