It has been reported that Facebook is going to add a feature to their app to allow users to view when friends are nearby. This technology has been used before. Where have we seen it before? Google Latitude, that's where. Want to try it out? Too bad, Google discontinued it a long time ago. Not really sure why. Maybe they didn't have many people using it. I know that the majority of my friends don't actively use Google+, so it's safe to say that the Facebook app will have more potential.
Now, I know what you're thinking. Facebook? No thanks, I don't want them knowing my location and telling everyone about where I am all the time. The good news is that you would have to actively turn on this feature. On the other hand, every time I update the app it seems to reset my preferences on location sharing in messaging. Guess they want you to share that.
How many of my friends would actually turn this on? Maybe a few. How many of them would know about the feature being added? Probably not that many, unless the new update explains to the users about the feature once they open the app. I don't see this becoming a big hit, as everyone is already wary of Facebook. Don't believe me? Go check out the responses to them buying Oculus Rift after it had been previously funded by crowd-sourcing.
I may turn the feature on once the app gets updated. Just to see how it works and how many use it. Won't be too interesting, but I do like the idea of using my GPS every once in a while. GPS technology is cool. Those satellites and space and such.
