Want to talk with people around you? You can use geographical hashtags! You can use https://whenwhere.cf to find yours and to read messages close to you.
To be fair, I am not in favor of forcing people to give their exact location on a website (although mine is completely static and doesn't save your info in any way) so I would really like it if someone can make a better tool to find your and someone else's local tag.
Also, I would love it if you build this in apps.
