Apple has announced an updated version of Safari at WWDC. The browser update adds a new home page featuring a Top Sites feature that stores all of your bookmarks and regularly read sites. Using a new bookmark bar, you can easily add and remove links to your Top Sites selection. They've also introduced a "Reading List" feature to the home page that allows you to quickly jump from story to story on the sites you read the most. Safari also now has Twitter and LinkedIn integration that allows you to monitor and open links shared in those services within the browser using another sidebar.
