I just found Alltop via a post on The Speed of Creativity blog. This post had a link to Liz Davis' blog "The Power of Educational Technology" and the post "Ten Tips for Growing Your Learning Network." I love being able to find these gems and pass them along to our family and consumer sciences teachers and students!
Alltop updates its stories every hour, so the searches are up-to-date and stories are current. Like any other web resource, you will need to determine the reliability of the articles/source. But, this might be a great tool when teachers or students need to find information on topics such as parenting, fitness, or careers.
On their home page, there is a video that will help explain how to use their site.
