The kind of mindless Internet advocacy Upworthy's been accused of promoting has inspired a new word: clicktivism. Clicktivists mistake gratification for meaning. They conflate feeling good (or self-satisfied or inspired or righteously indignant) with doing good. They watch a video of a kid sharing his lunch with another kid, forward it to their social networks or sign a petition, congratulate themselves on their political involvement, close the browser window, and diminish the definition of service for everyone.

Social media and clicktivism alone is [sic] not the silver bullet, but to discount the power of this as a tool is missing a giant opportunity, especially when trying to activate the masses.

A small, provisional victory for ‘clicktivists’ and yet according to Poland IP, it's demonstrable proof that a critical mass in Poland sees the internet as a legitimate means of expressing and organizing public dissent.

But that's not all… Internet activism, or clicktivism, comes in a variety of forms this month.

Notes
Basically you can say I am a "clicktivist"(who can click on the online petition only but not ready to go ahead to take part in any march or something else).
