I was reading into viral marketing strategies and found the 'One Red Paperclip' campaign. This guy, Kyle MacDonald started with a single paperclip, and 14 trades and one year later traded for a house. So I was wondering, realistically is there any sort of 'proven' method for this sort of campaign? I love the idea, I'm trying to think of it in terms of exchanging digital items like ebooks or domains... If anyone has ideas or has had success, big or small, let me know! I really get a kick out the general idea!
