according to the daily mail on november 16, mark zuckerberg, founder of facebook, unveiled his website's new messaging system and hailed the death of email on november 15.

　　the 26-year-old said it would go the way of the letter because it was too slow and too formal。

　　he showcased facebook's own version which integrates all web and text-based communications。

　　the service, perceived as a direct rival to google's gmail。

　　mr zuckerberg revealed that, as rumoured, the 500million people signed up to facebook will have access to a 'facebook.com' email address。

　　entire conversation histories going back years will also be saved into users' accounts and spam will be completely filtered out, he claimed。

　　'we don't think that a modern messaging system is going to be email,' zuckerberg said at a press conference in san francisco, 'we want people to be able to communicate in whatever way they choose: email, text or facebook message.'

　　facebook's new email system is modeled on instant messaging and on-line chat and will allow people to simplify their communications。

　　texts, email or instant messages will all come into one 'feed' and users can respond in any way they want。

　　one person could text a friend, for example, who will see the message come up on their facebook page instantly and respond via an instant message or email。

　　美国“趣味科学”网站17日报道称，一项针对1000名14到17岁女孩儿的研究发现，在网上她们会 “贬低”自己的某些方面，(被“贬”的方面包括智力和同情心)，同时会将自己描绘得更加“性感”和“疯狂”。

　　据了解，82%的女孩子称自己在现实生活中是“聪明”的，76%的人则称自己是“富有同情心的”，然而论及网络形象时，她们惯用的词汇往往是“有趣”甚至“搞笑”。

　　该项由美国女童子军(美国最大的女孩团体)发起的研究，还调查了女孩对自身和生活的满意度，以此评估她们的自尊程度。结果发现，自尊心较差的女孩子在网上和现实生活中的反差更大。

　　自尊心较强的女孩子中，18%的人称自己的网络形象和真实形象不符，而自尊心较差的团体中，这一比例高达33%。

　　研究人员发现，自尊心较差的女孩子更倾向于把自己的网络形象描述为“性感”(比例为22%，而自尊心较强者比例为14%)和“疯狂”(比例为35%，自尊心强者比例为28%)。
