World Press Freedom Day celebrates its 20th anniversary on Friday. It was first officially proclaimed during the UN General Assembly in 1993.

The theme for 2013 is Safe to Speak: Securing Freedom of Expression in All Media, a focus that includes securing a free and open internet.

Here bloggers from across the globe reflect on their work in the light of press freedom day.

Juanita Leon is a journalist and writer who blogs for the news website she founded - La Silla Vacia (The Empty Chair).

I have a blog about politics in Colombia. I blog because I like the freedom provided by the internet to investigate and write what you find, without having to work for someone else.

In many areas of Colombia press freedom is still just an aspiration

I care about public issues in Colombia, and specifically how power is exercised. Why? Because I think that part of having power in Colombia means that you can choose what is said about you - and what is kept secret. I want to break that.

We haven't really found a commercial business model for bloggers in Colombia yet, and still depend in great part on international co-operation. But we feel we have had the freedom to tell everything we know, which is great.

I wouldn't say that it is a privilege that every Colombian has. In Bogota we are a lot more protected. In many areas of Colombia still under the control of illegal groups or under the intimidation of corrupt politicians or armed officials, press freedom is still just an aspiration.
