Yesterday the code.flickr blog wrote about their new Geofences feature that allows users to create virtual fences around certain locations so that their geotagged photos can maintain some semblance of automated privacy.
I think it is a great idea. You simply go to your account’s privacy page, select a location and tell them how large a circular fence you want to make. Then you assign access to the fence to your own groups – Friends & Family or School Contacts, for example.
However, it does seem to me that drawing a fence also kinda tells people you are keeping out that the location in question is important to you for some reason.
