In a way, Amplify is what I had hoped Clipmarks would be: in addition to giving you an easy way to take entire clippings of the Web that you can return to and review later, the service allows you to share those interesting tidbits with the world. This way you give other people a way to interact with you, comment on your clippings, and see what you're reading on the Web that you think is interesting and worth sharing. Since Amplify allows you to hook into your Twitter or Facebook account, the service doesn't have to compete with those networks for attention and can compliment them instead.
