新浪财经讯 美股周三大幅下跌，标准普尔500指数与纳指均创5年新低，道指创5年来收盘新低。美国汽车制造商的困境、欠佳的经济数据、美联储的悲观预期以及市场未能守住关键支撑位给空头提供了足够的理由。主要股指均以盘中低点报收，成交略高于往常，道指下跌了5.1%，纳指下跌了6.5%，标准普尔500指数下跌了6.1%。

Social Browsing: Diigo Toolbar now enables a social browsing experience. While you are reading a web page, the Diigo sidebar shows you who else has bookmarked or commented on this page, who else has bookmarked other pages on the same site, and what other similar pages and sites they have bookmarked. Personalized Social Content: Diigo as a source of social content has been substantially enhanced. You can now find and subscribe to the most recent or most popular bookmarks under any set of tags. You can also discover interesting content through your friends. Based on your bookmarking activities, Diigo provides recommended news and resources personalized to your interests. Social Information Networking: Rich social networking features have been tightly integrated with social bookmarking and annotation to enable more meaningful social connections and intellectual exchanges. So you can keep in touch and interact with friends through readings and annotations non-intrusively and with little extra effort. Multiple ways are provided for sharing information with friends both on Diigo and elsewhere, with varying degrees of non-intrusiveness. You can also find "people like me" - those who are closest to you in interests, or search people by tags or sites to find others who share certain specific interests with you. Once you find people of interest to you, you can connect with them in multiple ways: invite them to add you as a friend, send them messages, invite them to a group, or simply add them to your watchlist.

"The new Diigo combines the best of social networking, bookmarking, highlighting, and annotating to let people discover, save, and share the information that is important to them personally or professionally," said Dr. Wade Ren, CEO of Diigo. "Not only can people find a collective repository of searchable and relevant information, but they can markup and save information along the way - all while keeping in touch with friends and connecting with like-minded people."
