Well done to MobLog UK Team for the inspired site We Are Not Afraid.

The idea is for Londoners and everyone around the world to express
solidarity for last week’s bombings and show the perpetrators that
ordinary people will not be cowed by these kinds of events. All people
have to do is snap a photo of themselves, preferably incorporating
the slogan "We Are Not Afraid" and it gets on the website.

Apart from being a very noble concept,  it’s also a great
illustration of how technology can be used to harness and spread an
idea incredibly quickly.

Blogging software means that you can throw up a website in a couple
of minutes - something that until recently would have taken a
professional maybe a month to do.

The idea then spreads virally in a matter of hours, through posts
such as this, but also as people tell their friends by sms, email,
phone and face to face.

Google and other search engines make the site incredibly easy to
find. It’s already number 5 result on Google if you just search for
"afraid" and an unequivocal number one for "we are not afraid".

Then digital photography, including images taken with our mobile phones, is used to capture the moment.

It’s simple, easy-to-use, empowers ordinary people and their communities and is frighteningly fast.
