Silicon Valley visionary Guy Kawasaki has helped launch a simple but useful window into “all the top sites” found around the web including a section dedicated to the best sites covering the green revolution. Alltop.com organizes headline feeds from leading sites across 80+ categories.

Green.alltop.com is where you'll find the recommended green news and information sites. We’re pleased to find several Matter Network publishing partners appearing on the list, including TerraPass Blog, GreenUpgrader, EcoGeek, Inhabitat, RiverWired, Triple Pundit and Matter Network itself.

Apparently determing the “top” listings is largely a judgment call by the Alltop team. According to the site, they rely upon “Google searches, review of the sites’ and blogs’ content, researchers, and our “gut” plus the recommendations of the Twitter community, owners of the sites and blogs, and people who care enough to write to us.” They also credit the Twitter social network as having been "the single biggest factor in the quality of Alltop."

Thus, a site's positioning on the list may not necessarily reflect that site's actual traffic rankings or popularity among demographic groups outside those of the influencers. Nonetheless Alltop seems useful as a way to discover interesting sites and to get a quick scan of current stories.
