Thank you all!
I also have a free invite link to Kiva if you get in really quick - I think they're going to run out soon: http://kiva.org/invitedby/deborah2989. This lends you US$25-worth of electrons to lend to someone somewhere as part of a microloan scheme. Repayments will go back to Kiva, who are clearly hoping you'll get hooked on the fun of it as I have.
(Yes I also know microlending has issues. I think Kiva does fairly well avoiding many of these but no doubt opinions vary.)
