The SAET weblog is astounding in form and function - the information provided there on the relief efforts in South-East Asia is so very valuable. Visit and donate via one of the Links.
Thanks to Constantin -- who also has a great list of related links -- for pointing it out to me.
Meanwhile, Benjamin is investigating the effectiveness/efficiency of various charities here.
Thanks to boing boing for that link.
You can also one-click donate to the American Red Cross on Amazon's homepage.
