Activism vs slacktivism Does technology increase activism?

Does it help?

Is it a mirage? In the US:

SMS remains the key technology

But needs to take the user to live sites Who is the target? How important?

Over 80% of smartphone/tablet users are registeredvoters

Will YOU give them your phone #?

Potential for new biologicaland chemical weapons.

An arms race? Military development in the

civil sector

Is there a problem whennano is used for militaryends?
