Yahoo! Search blog: Saving, Sharing, and Syndicating Search via My Web
“Today, we launched a ‘My Web’, a new personal search engine fully integrated with Yahoo! Search. My Web is based on a very simple principle – a search engine should enable you to define and use the information that’s important to you. Specifically, My Web enables you to find the information relevant to you, save it, share it, add your own notes to it, and easily find it again, whether it’s three days or three months later.“
I’ve been using the beta for several months and it is handy. I stick stuff on it that I need for later, replacing some of the function of my blog.
