"Activism-lite"

In an article in last weekend's Australian (Twitter-led revolution reveals a character limit), Geoff Elliott uses the term "activism-lite" to describe the way social-media users rally in support of a cause.

I think it's a pretty apt description of the causes we "support" with no more than a mouse click.

The more groups we join on Facebook, the more implausible the notion that our support goes any further than a flippant click and a desire to further supplement our profile with an array of ideologies we're proud to call our own.

I'm not saying it's bad to voice support in this way (clicking "like" in response to a comment is easier than composing an intelligible response, and seems better than offering none), I'm just wondering whether the ease with which we can do so online means we "rally" more and, feeling as though we've done our bit, do less.
