Friends Write Tweets Together With Retailer's App

Wait, I missed International Friendship Day? I guess if I had any friends, I would've known. In most countries it's the first Sunday in August. It's July 20 in Argentina (where it's known simply as Día del Amigo), and this year it inspired a novel campaign from women's fashion retailer Todomoda, ad agency +Castro and advertising students at Escuela Superior de Creativos Publicitarios—allowing friends to literally share tweets. An app allowed one friend to start a 140-character tweet and a second friend to finish it—it then appeared in both feeds.
