Let me tell you, this is as good as it gets for browsers.  Chrome is screaming fast, and now, we get extension love.  So, you go here, and click on what you like, and they install and show up in the top right corner as shown.  So far, I have a dozen up and running, and you do have to run the Dev Channel version of Chrome to make these go.  Foxmarks has created a Chrome extension, the popular Firefox add-on that synchs your bookmarks. There’s a drop down Wikipedia box..a drop down Google Calendar box..a drop down Google Tasks button..and similarly designed buttons for Google News, Maps, AccuWeather, a clock, and a Facebook/Twitter feed thing called Brizzly, which Arrington adores.  This is just the tip of the iceberg, and the browser rules have just changed.  Firefox now has legitimate competition.
