As BlogWorld kicks off in Las Vegas later today, the folks over at change.org, in partnership with several other prominent organizations such as Greenpeace, The Nature Conservancy, and WWF, launched Blog Action Day.
Blog Action Day is an annual event held every October 15 that unites the world’s bloggers in posting about the same issue on the same day with the aim of sparking discussion around an issue of global importance. Blog Action Day 2009 will be one of the largest-ever social change events on the web.
This year’s focus is on the growing concern over climate change. As of this morning, 8,922 blogs are participating—including 3p—representing 148 countries, and a combined readership of over 12.5 million people.
