The Alltop page shows the headlines of the latest posts from many good school-related blogs. By placing the cursor on the headline, you’ll be shown the first paragraph of the post. Alltop is a pretty massive “aggregator” of blogs from multiple categories.
Alltop has just introduced a personalization feature to mixed reviews. You can read a positive review at Free Tech For Teachers and a less enthusiastic one at TechCrunch. I tend to be more on the positive-side, even though you can only include blogs in your own personal page that are already on Alltop’s site. It’s a good place for students and newcomers to the Internet to start learning what’s out there.
