Good article in Businessweek Monday about Nike+, the social performance tracking service for devoted runners. Excellent example of "Structured Collaboration" for more useful and "brand-safe" user-generated content ("UGC").
- valuable information shared: performance data (mileage, etc.)
- logical groups to share within (running buddies, virtual races)
- ease of contribution and consumption (data synced when you sync your iPod, charts make reading data easier)
