I’ve been using FriendFeed for awhile and if you subscribe to my feed you’ll see just about everything that I do online. My feed includes all the articles I bookmark with delicious. When I write a new blog post it automatically shares it on my feed. Every time I tweet on Twitter and when I update my status on Facebook, they’re included here. When I add a video to my favorites on YouTube it is shared here as well. Currently there are 58 different sites that you can link to your FriendFeed, so it’s like the one stop shopping place for everything online!

FriendFeed also has a search function where someone without even registering on the site, can easily search all FriendFeed updates.

Facebook has been in the news quite a bit this week which they started off with the announcement that they have acquired the social-identity aggregator, FriendFeed.

Google 的特殊功能 查找 Flash 文件 查找Flash文件，只需搜索“关键词 filetype:swf”。 Google已经可以支持13种非HTML文件的搜索。除了PDF文档，Google现在还可以搜索Microsoft Office (doc, ppt, xls, rtf） 、Shockwave Flash (swf)、PostScript (ps)和其它类型文档。新的文档类型只要与用户的搜索相关，就会自动显示在搜索结果中。 例如，如果您只想查找 PDF或Flash 文件，而不要一般网页，只需搜索“关键词 filetype:pdf” 或“关键词 filetype:swf”就可以了。 Google同时也提供用户不同类型文件的“HTML版”，方便用户在即使没有安装相应应用程序的情况下阅读各种类型文件的内容。用“HTML版”阅读也能帮助用户防范某些类型的文档中可能带来的病毒。 总的来说，不同类型文件类型的搜索大大拓宽了Google用户能在网上获得的知识内容。Google将不断拓展新的可搜索文件种类。
