What kind of Ｔweet will be displayed on my Air Tweet?

A Ｔweet displayed on Air Tweet on Liveview is the most recent Tweet from a user whose Twitter location settings have been set somewhere close to you. (The user must have his/her location settings registered on Twitter)

If the Twitter user has his/her latitude/longitude information registered, his/her tweet will be displayed even if he/she is not a Sekai Camera user.
