Amazon and Twitter are going to make shopping easier on the latter's social media platform. When Twitter users observe a tweet that moves them to purchase, they can reply with the hashtag #AmazonCart to add the product to their shopping cart on Amazon.com. (Consumers have to sync their Twitter and Amazon accounts first.)
Any way you shake it, that seems to technologically advance the idea of social shopping. At the same time, the development appears to invite tweet-jacking since, per Twitter, the hashtag will be open season in concerns to Promoted Tweet bidders who buy the platform's search-like inventory against the term.
