Motivation Taxonomy : Motivation Taxonomy “I tag photos with what I think might be interesting to other people, stuff I think people will like” “I know that tagging can connect my photos to activities, and get more interest” “I want to look at all [my neighborhood’s] tags. … That’s definitely a reason I’m putting these tags in ” “...at night, by the fires all around the market, ... at each word that one man says -- such as 'wolf', 'sister', 'hidden treasure', 'battle', 'scabies', 'lovers' -- the others tell, each one, his tale of wolves, sisters, treasures, scabies, lovers, battles.” -- Italo Calvino, Invisible Cities
Motivation Taxonomy : Motivation Taxonomy “…so that my friends can see what I am up to” I can tell my mom [with the tag] “look, we went to…” “I left reviews of places – like at the airport, when my flight was delayed, I tagged “Aloha Air sucks.”
