The good thing about the Facebook Camera is that it makes uploading images to Facebook really nice! It’s so easy to tag your friends and family, you upload to a specific album or create a new album, and you can tag the location the photo was taken.
So that regard, it is one of the mor useful apps for uploading to Facebook. It’s just too bad that’s your only option.
Actually, now that I think about it, it’s odd that you can’t upload to Instagram with it.
