I love Touchnote. I can send a photo postcard (with my photo on it) from phone or computer anywhere in the world for a dollar. I can snap a shot of a party or something odd with my phone and with only a few clicks have it on its way, with a note, to my children who are scattered about the world.
Touchnote pulls addresses from my phone's contacts (or -- they say -- from one's facebook friends. Haven't tried that.) Or you can enter an address.
The ability to do this amazes me. Touchnote is fun. It is useful. I think it's cheap.
And Touchnote has the best customer service I have experienced in years. I'm told that their executives take turns doing customer service -- which seems to be an excellent way for the folks in charge to keep tabs on what is actually going on between customers and the company they are running.
(Touchnote currently has a bunch of forms available to make custom photo Christmas cards, too.)
