It's always funny how after saving the world multiple times and essentially being at the call of Celestia's will, the mane 6 aren't really recognized at all when they travel to different locations. We saw in the Celestia and Luna vacation episode that ponies very much love taking pictures of royalty, so why don't they know about Twilight and friends at all?
Is it due to the lack of communication ability in Equestria? Or no types of national news service to spread word on things? Or do they just not care?
