I have just started using Scoop It today and I must admit I have started scooping sites and I am liking it, see http://www.scoop.it/u/diane-louise-bell
Scoop It is a tool for curating websites and content, you can create folders on different topics and bookmark different resources there. It has a really nice, smart interface and looks visually attractive. You can easily scoop content by installing a Scoop It bookmarklet on your browser and then just clicking on it to bookmark a site. I had no problems installing this which was great. You can also link it to Twitter and Facebook and post entries there. I think it could be a useful promotional tool and good for saving Slideshares etc. It also has a Twitter feed https://twitter.com/scoopit
