As you may know, Flickr is my photo-sharing site of choice due to its institutional community among geeks going back for more than 5 years. However, many of us geeks are often disappointed in Flickr's inability to evolve ever since Yahoo took over, with the site stagnating in design and features for years. Due to this, I'm always hopeful when I do see them add new features because I become optimistic that perhaps Yahoo is putting more focus on development at Flickr. Today's announcement from Flickr introduces a new feature they're calling "Geofences". From their annoucnement:

Geofences are special locations that deserve their own geo privacy settings. For example, you might want to create a geofence around the your “home” or “school” that only allows “Friends and Family” to see the location of the photos you geotag in that area. So the next time you upload a photo with a geotag in the radius of a geofence, it will follow the default geo privacy you’ve designated for that hotspot. That way, you can easily make sure that only people you trust can see the location of photos taken inside your house or any other sensitive areas while still showing the world exactly where you had those amazing cheese covered duck fat fries. If Flickr can continue to hold onto their community as it stands today, and with the further proliferation of cameras with GPS capabilities, I think features like this could be very powerful for users.
