We're thinking of doing something like this, where local blogs are displayed on FourteenTeeth. Local blogs would be automatically displayed based on IP address (or a chosen manually-entered location) if available for an area. For example, while browsing FourteenTeeth in NYC, you might get local blogs such as Bike Blog NYC, while in Seattle, you might get ZLOG and Go Means Go.
We'd initially go live with a few locations (Seattle, SF, NYC, UK, etc.), and add more as time goes on (people would be able to suggest blogs quickly and easily).
Thoughts? Suggestions? I'd love to hear what everyone thinks about this.
