Huge numbers of people gathered all over Colombia as part of a massive protest condemning the practices of the Farc:

Some estimates put the number of people protesting in Bogota at between 500,000 and two million.

Thousands more protested elsewhere in Colombia, and in close to 100 other cities around the world.

At the root of these protests? Why Facebook, of course:

The protest was started less than a month ago on the social networking website Facebook by a 33-year-old engineer, Oscar Morales, from his home in Barranquilla on Colombia’s Caribbean coast.

Over 250,000 Facebook users signed on, and the movement was taken up by newspapers and radio and television stations across the country.

And here we were thinking Facebook was little more than a way to “network” “socially” while actually avoiding all those friends we secretly can’t stand.
