You may already have all of this information, but just in case you don't, I'm giving money to Doctors Without Borders and Oxfam. As Loren pointed out earlier, sustained giving is actually the really helpful thing, so if you don't have a lot to give, consider waiting a little bit and then giving money.
Tsnumani Help is a blog with lots of ongoing information in multiple languages.

After the new year... some non-tsunami related blogging (it just all seems a little pointless and decadent to talk about anything else right now)
