"I would be surprised if Robert were the first one to try this strategy on FriendFeed and Twitter. FriendFeed, since the beginning, has let people import their Amazon Wish Lists, as you can see when you check my feed, though almost all were done in late 2007. http://friendfeed.com/louisgr... It wouldn't be too difficult for FriendFeed to either enable their affiliate link for all Amazon purchases, or to let users define their own, I am guessing. But I think that wouldn't be enough for the service to call a business model, as I doubt enough people click through and by for their social media friends." - Louis Gray
