Updated at 2:30 p.m. PDT to include more details about how location information is displayed and gathered in JuiceCaster, and more specific information about the feature's launch.
First came mobile social networks, then came geotagging. Since location-based features take advantage of your ever-portable mobile phone to pin your activities to a place, we weren't surprised to learn that on Wednesday JuiceCaster (reviewed) added automatic geo-anchors to its multimedia sharing service.
Soon JuiceCaster photos and videos that are auto-posted to Facebook, MySpace, Twitter, Blogger, YouTube, and other sites will share the individual's street name and city. Friends who keep a close eye on geotags can use that to gain contextual understanding of the scene or use it to "bump into" friends nearby. In an important distinction, JuiceCaster's location feature is designed to be optional and visible only to confirmed friends.
A final tidbit called "Who was here?" attaches further meaning to a place. Selecting it from the menu will call together a list of photos and videos for that most-wanted location. You'll be able to browse through the content or add your own. You'll also be able to seek out geotagged photos and videos by location, which may muscle up JuiceCaster's searching accuracy.
JuiceCaster's new location-based functionality will become available "shortly" for GPS-enabled cell phones running on the BREW platform before rolling out to other carriers' GPS phones.
