Firefox extention for educators-Diigo

I’ve been using Diigo for a couple of weeks now and am loving it. That’s way it’s making my recommendation for a Firefox extension.

Social search has a brand new contender - Diigo Currently social search appears to be the hottest topic on the internet. The theory is that more useful and meaningful search results can be gathered regarding the true value of sites by getting users to recommend websites rather than utilising a series of computer generated algorithms.Traditional search engine results, such as those supplied by Google and Yahoo!, are primarily based on objective criteria such as counts of the backlinks from other sites. These links are seen as votes on the importance of that page for a given set of criteria. Social search allows users to assign their own votes regarding which sites are worthwhile, by sharing bookmarks of favourite sites, adding their own subject tagging, or making annotations to listings. This creates a more subjective set of results, which some feel can more accurately reflect which sites are most meaningful for particular search terms. The concept of social search has been continually evolving since social bookmark sites like Del.icio.us and Shadows first appeared through to more involved services such the social networking sites MySpace and MyWeb, or the social news source Digg.Now a new player has appeared on the scene. Diigo (Digest of Internet Information, Groups and Other stuff) which was launched on Monday aims to combine a number of features such as shared bookmarking, blogging and web page tagging into a single service along with a powerful toolbar search tool.Diigo promotes itself as an online social research and "social annotation" tool, allowing users to:"Collect, share and interact on online information from anywhere”. By letting users quickly create their own comment on sites as well as highlight, clip or make sticky-notes for webpages, and providing access to organic search or their own social search results, which can be adjusted to suite the users preferences, Diigo has created a service with several interesting resource sharing and community promotion features. By taking onboard search features normally associated with search toolbar extension filters such as the ability to restrict keyword searches to the site you're currently viewing, the usability of the search functions have been increased to make this a useful service regardless of whether the user is looking to fully immerse themselves in the online social environment.While there is currently no direct official link between social search results and organic results obtained on the traditional search engines, many users have recently started to find information from the likes of MySpace creeping in. With Google and Yahoo! both having their own networks it looks likely that more of the features and results will either be merged together or be offered alongside each other so that you can get different sets of results depending on your preferred search method.Whether Diigo is here to stay or is set to quickly disappear like many other social search sites, remains to be seen, however the simple customisable interface and powerful set of useful tools make this one of the best offerings for some time.

什么是Diigo？Diigo是“Digest of Internet Information, Groups and Other stuff”的缩写，当你在网上浏览的时候，你可以对你认为重要的信息和文章段落进行高亮标注甚至对其增加一个你的批注，看，现在圈阅文章也不是纸媒介的专利了。 而当你对这些信息进行批注和高亮标示的时候，这些信息可以自动的选择加入到你的收藏里，而加入到你收藏的这些信息不仅仅只是一个收藏夹的效果，同时还可以分享给其他人，这些信息以及你的批注可以分类并通过Diigo Toolbar进行搜索，他人也可以对这些信息进行评价（又一个social bookmark?），你也可以很方便的通过Diigo Toolbar将你的信息发送到BLOG上去。作为一个web2.0服务，Diigo同样也支持tags。 我的一个朋友曾经几次推荐这个服务给我，但是我一直因为要安装toolbar而没有使用（我不喜欢在我的Firefox上安装工具栏），然而Diigo有一个Diigolet我以前没注意到，这个小东西应该只是一个js文件，只要把它拖进你的bookmark toolbar就可以了，一点也不影响美观。在你浏览网站的只要点击这个按钮，就会弹出一个Diigo的信息栏，通过这个信息栏你可以使用Diigo所有的基本功能。
