This blogger has always been a big fan of Global Voices, an initative promoting blogging in different languages and different regions. Zemanta is a campaign to help special causes to blogger.
I vote for Global Voices Advocacy, because I think it is a major tool and organisation in the fight for freedom of expression. Freedom of expression gets more and more threatened all over the world, through national firewalls, crackdown on journalists and blogger, threats of all kinds on free speech.
This blog post is part of Zemanta's “Blogging For a Cause” (http://www.zemanta.com/bloggingforacause/) campaign to raise awareness and funds for worthy causes that bloggers care about.
