I'd encourage everyone to head to the site above and give what you can to the effort. I've made my donation (and if a grad student in the humanities can help out, most anyone can). I'd also suggest donating online-- the phones are pretty busy.
Just for kicks, I thought I'd take a look at how many of the right-wing blog biggies are following suit and encouraging people to donate to the Red Cross (or anyone). I found one-- Michelle Malkin-- and that's it. Granted, I only checked about nine, but that isn't much of a record.

Once again, you've got to hand it to all those bleeding-heart sodomites for bailing out the red states....
UPDATE: The Red Cross' follow-up message to my donation contained the following not-so-fun facts. Read 'em and see if you can't rustle up at least a measly 20 bucks to feed a few people for a day:
