Twitter integrated shopping.....meet Amazon Cart

So it seems the wave of companies to incorporate social media into their businesses, well Amazon has taken it a step further and introduced #AmazonCart. The idea is simple, you (the twitter user) see a tweet reply with the hashtag #AmazonCart and the item is then added to your shopping cart. In order for the hashtag to work, you need to sync your Amazon account with your twitter account. So do you think this is a good thing, or does it just encourage laziness? I would think that if your intent is to shop then you would be on Amazon? Will you be using this? ~ChicDivaGeek
