Fantastic Freebies: Send someone a postcard!
Enter HippoPost.com: You fill out the form, choose an image, type in your message, and they send it to whomever you want. They even pay the postage, and stick an advertisement on it to, hopefully, eke out a small profit.
With postage rates increasing so fast that it's cheaper to hire a Wal-Mart employee to bicycle across the country and hand-deliver a postcard, I can see hippopost catching on big time. Give it a try! It's a nice alternative to an email.
