Since I don't have "Second Life" or anything like that on my computer, I was checking out the Nike+ website, and there's recently been an option for a "My Nike+ Mini". So I clicked and sure enough... it's an avatar!
I designed my avatar in about 25 seconds (maybe less) and posted it for everyone to see. Since the "My Last 5 Runs" isn't working regularly, but the "My longest Run" is... I thought people could see my last run and my avatar's reaction to the run. In fact, if I don't run, the avatar will mock me to try to encourage more running. I think I'll like that, if even for the humor in it.
