But there is one thing missing, which is being able to store bookmarks and share them with friends. Sure, there are a few great social networking sites out there, del.icio.us being one of them. But they lack the ability to highlight parts of a story and add sticky notes that stays on that website. Diigo offers these two brilliant features via their Toolbar. It’s just like when you read an interesting book and highlight the important parts and somtimes add a comment via a Post-It note. Not another Toolbar you say. Well, Diigo has actually replaced all my other toolbars. Flock offers a toolbar with favorites which is more than enough to cover my favorite online destination hangouts: Yahoo!, Google, Amazon, Wikipedia et cetera. All other bookmarks are tagged in Diigo and News I get directly to Flock via RSS feeds.
