Boston Marathon Bombings

Selected quotes from CNN discussion
• “We could wonder if the NY Post would
have had this terribly irresponsible
coverage if it weren't for Reddit”
• “There were rational people on Reddit
and social media”
• “Do you think everything you read on Twitter
is real? -No, but it is hard to know”

Motivation
• It might be the case that posting funny
memes and verifying information using
social media require different tools
• The repertoire of mass-interaction
mechanisms we know of is quite limited

The interaction mechanisms we
know of are quite rudimentary
We can design specialized
platforms for mass interaction
for specialized goals
