Today, several hundred bloggers (probably by the time you read this it will be over a thousand) are banding together in a Blog relief effort. The idea is to post a charity which is working for Katrina relief, donate, and urge your readers to donate to it also. This effort is being organized by The Truth Laid Bear and Instapundit.
My charity is:
Habitat for Humanity
Once the initial shock and clean-up are over, thousands of people will have lost their homes. Habitat for Humanity has spent 30 years helping the homeless and poor of our world into homes. Their experience will be needed in the Gulf states to move storm victims as quickly as possible into new residences.
Keep hoping for the best.
