What would happen if every blog published posts discussing the same issue, on the same day?

On October 15th, 2007, we can find out if blogging can make a difference to the world. The idea, to which some of the world's biggest blogs have already signed up, is to post about the environment, in their own particular way that is relevant to their own topics, in an effort to get everyone talking towards a better future.

It is easy to take part: Simply go the the Blog Action Day homepage and register your blog. You can also check out Blog Action Day's list of resources, to help you think about how you can make environmental issues relevant to your blog topic.

There are also lots of cool banners available for your blog, such as this one.
