Yes, I think everyone is on the right track here by asking organizations we love and respect to accept witcoins.  I just sent a message to the ACLU asking them
if they had an address:
Hi,
  I would like to make a donation to ACLU for all of the great things that it does to protect our liberties.  I use Bitcoin to send money over the internet but I don't see a Bitcoin address to use on your "Make Additional Gift" page.  Do you have a Bitcoin address I could use?

Thanks,

If others continue to ask they'll take notice and put an address up, and then others who also want to support the ACLU or whichever organization it is will see this and want to learn more about Bitcoins.
