Postcard.fm Sends Custom MP3 Ecards [Ecards]
You can spend a good chunk of time searching the web for an ecard that isn't annoying, cheesy, ad-ridden, or some combination of all three. Or you can grab a picture, choose a song, and send a super-clean, customized ecard through Postcard.fm. Simply upload an image file and MP3 to the free, no-registration-required site, add a message, and mail it out. The recipient gets a link to your e-postcard page, with no ads in sight (at least for now). This means you can be as cute, clever, snarky, or affectionate as you want, rather than letting some oddly-shaped critters express your wishes.
