Alltop which was founded by Guy Kawasaki has a very unique purpose:
We help you explore your passions by collecting stories from “all the top” sites on the web. We’ve grouped these collections — “aggregations” — into individual Alltop sites based on topics such as environment, photography, science, Muslim, celebrity gossip, military, fashion, gaming, sports, politics, automobiles, and Macintosh. At each Alltop site, we display the headlines of the latest stories from dozens of sites and blogs.
You can think of an Alltop site as a “digital magazine rack” of the Internet. To be clear, Alltop sites are starting points—they are not destinations per se. The bottom line is that we are trying to enhance your online reading by both displaying stories from the sites that you’re already visiting and helping you discover sites that you didn’t know existed. In other words, our goal is the “cessation of Internet stagnation” by providing “aggregation without aggravation.”
Cynthia Ware explains the significance of Alltop here, much better than I can.
Thanks to Guy Kawasaki and Robert Yang for their work on this and for allowing me to be a part of it.
