If you're on Facebook, you've probably seen this update from some of your friends:

Change your Facebook profile picture to a cartoon character from your childhood and invite your friends to do the same for the NSPCC. Until Monday (December 6th) there should be no human faces on Facebook but an invasion of memories. This is [a] campaign to stop violence against children.

I started seeing this pop up in my news feed from a bunch of my friends on Saturday. Many of my friends started changing their photos without posting the update.

I didn't.

Some of my friends were outraged by my comment. A few realised what I was getting at.

Show your apathy with a Twibbon or Profile Badge today!

People are outraged by many things - child abuse, threats of funding cuts to services, huge losses of jobs, investment banking, politics - but very few people are actually moved to the point where they get off their arses and do something about it.

Some people will even change the entire colour scheme of their websites for a day, or even a month. I would wager that the majority of individuals who make these kinds of changes won't give a second thought to the actual cause, nor will they donate their time, skills or money to anything that might, y'know, actually help.

What did you do? You changed a few pixels of your profile photo.

Well done.
