in 5 points that say:dont build for location,build for the person
1: The Infamous “Radius”
location based services remind me of

thats you
thats the view of the worldyour location-service gives you
thats where yourfavourite band isplaying tonight
thats therestaurant youwould love
thats the thing youneed right now
1: the radius opts for laziness(close) over preference (lets go!)dont build for location, build for the person
2: The Ontology of Location
sometimes i care about here:
sometimes, my city:
other times, other cities
or many cities
2: information about “place” cancover several layersdont build for location, build for the person
3: Discovery vs. History
e.g., i want a coffee
lets search...
3: location ignores the usersexperience and knowledgedont build for location, build for the person
4: Relevance & Explanations
i dont commute withthe Central Line.
Dave C. isnt my friend :(
i was free 4 hours agotoo.
people who go   to train stationsgo to China Town.
4: location does not meanrelevant, timely, or meaningfuldont build for location, build for the person
5: the data problem
social signallingvs. locationquality
are all ratingsmeaningful?
privacy nightmare
5: “location data” doesnt mean“appropriate”dont build for location, build for the person
