I'm going with the advice of Mr. Dodo over at Lifelike Pundits. The Salvation Army makes sense to me but there are many fine charties to donate to, so head over to Instapundit and look at the list of options.
IMPORTANT: After you contribute, go here to log your site and contribution. TTLB is tracking it. Thanks.
UPDATE: As of 2:00 pm pst, 1050 blogs have joined in. Wow.
