How Does it Work

The new syntax is pretty easy to learn. Every tweet should contain at least one main tag like #need [explain need], #offering or #injured [name]. You can find a full list of main tags here. In addition, tweets can also have data tags like #name [name], #loc [location] or #contact [email, phone etc.]. These tweets can also contain often-used keywords that don’t need the hashtag sign like food, supplies, road, hospital or help.

Examples

Here are some real-world examples of this new syntax being used in Haiti:

  • #haiti #need security #loc General Hospital PAP #contact @thehatian
  • #haiti #need water #loc Orphanage Foyer de Sion #contact @robinbauer #src @AnnCurry
  • Can you deliver beans rice water to orphanage? #Haiti #Need Food #Contact: @childhopeintl #Loc: Delmas 75, Rue Cassagnol #14, PaP BLESS YOU
