You still see all those social media posts like "Anyone tips for Paris?" Very inefficient as you are dependent on who will be kind enough to actually share a relevant tip, instead of "Go by plane!". And how to save those locations?
With CityShare you can just search for 'Paris' and directly see tips from friends and add them to your own collection of favorite places. It therefore saves an awful lot of time, which can better be spent on traveling! Think about 'Pinterest or Spotify for travel'!
