今日技术焦点：是本周最引人关注的新创公司？还是Twitter创始人回归？

    • 日前，一款名为Color的免费手机应用程序引起了人们极大关注。这款程序旨在创造一种能充分利用智能手机独特技术的社交体验。用户能在虚拟日记本里分享和存储图片及视频。他们除了查看自己的多媒体资料外，还能访问在自己附近、与自己同时登陆的其它用户所分享的多媒体资料。Color的团队同样引起大家关注：其成员包括来自Lala的比尔•阮、来自BillShrink的皮特•菲姆以及LinkedIn前首席科学家DJ•佩蒂尔。Color在软件发布前获得了来自红杉资本（Sequoia Capital）、贝恩资本（Bain Capital）以及硅谷银行（Silicon Valley Bank）的4100万美元投资。（《财富》）

    • 苹果（Apple）负责Mac软件工程的高级副总裁伯特兰•瑟兰德宣布离职。瑟兰德同时还是Mac OSX操作系统的架构师之一。他表示：“我同史蒂夫•乔布斯共事22年。在NeXT和苹果，我度过了产品开发生涯里无以伦比的时光。不过现在，我希望将更多精力放在科学而不是产品上。”格雷格•费得里尼将接替瑟兰德的职位。（《财富》）

    • 另外，Twitter创始人兼Square联合创始人杰克•多尔塞可能重返社交网络领域。虽然有消息称他将担任Twitter首席执行官，但多尔塞更可能担任类似首席产品官的职位。（Business Insider）

    • 雅虎（Yahoo）推出搜索指导（Search Direct），这项搜索引擎技术和谷歌的即时搜索（Google Instant）类似——当你输入搜索主题时，下拉菜单里会显示建议结果。不过，雅虎负责搜索产品的高级副总裁沙斯•塞斯认为这两种技术并不相同。他表示，“我们致力于提供答案而不是链接。我们认为下一代搜索引擎，无论是传统互联网还是移动互联网，所追求的是答案而非链接。”（TechCrunch）

    • 谷歌（Google）悄悄推出全本在线杂志《思考季刊》（Think Quarterly）。该杂志在英国制作，每季度出版，目标是“在繁忙的世界中找到喘息空间”。第一期杂志有68页，主要讨论数据及其对商业的影响。（Mashable）

    • 据来自TechCrunch和ComScore的消息，MySpace的流量下滑速度正在加快。2011年1月和2月，MySpace的全球独立访客数量下滑了14.4%，从7300万降至6300万。这一数字仅为一年前的一半。（TechCrunch）

    • Windows Phone 7的用户，欢呼雀跃吧！上周Windows Phone 7更新正式发布，你现在也许能像其它智能手机用户一样，享受复制、粘贴功能了。（Digital Trends）

    • 你打算在T-Mobile被美国电话电报公司（AT&T）收购之前，结束与前者的合约？你绝不是一个人在战斗！（《财富》）

    • This week, the startup everyone's buzzing about is Color, a free mobile app aimed at creating a social experience that maximizes the smart phone's unique technology. Users share and store photos and videos in visual diaries -- besides being able to view their own media, they can also view media shared by other users nearby and logged around the same time. Color's also worth noting because of its team -- Bill Nguyen of Lala, Peter Pham of BillShrink, and DJ Patil, formerly chief scientist of LinkedIn -- and $41 million pre-launch funding from Sequoia Capital, Bain Capital, and Silicon Valley Bank.

    • Apple senior vice president of Mac software engineering Bertrand Serland, one of the architects of the Mac OSX operating system, is leaving. "I've worked with Steve [Jobs] for 22 years and have had an incredible time developing products at both NeXT and Apple, but at this point, I want to focus less on products and more on science." Craig Federighi will take over. (Fortune)

    • Meanwhile, Twitter creator and Square co-founder Jack Dorsey could reportedly return to the social network. Though the title of CEO has been thrown around, it's much more likely he'd serve as something like Chief Product Officer. (Business Insider)

    • Yahoo announced Search Direct, a search engine feature resembling Google Instant where suggested results populate a drop down window as you type in search topics. Yahoo SVP of Search Products Shashi Seth notes the differences between the two, however. "They're very different products," he said. "We're focused on providing answers, not links. Google Instant is focused on providing more links, faster. Not answers. We believe the next generation of search regardless of whether it's on the web or mobile, they're looking for answers, not links." (TechCrunch)

    • Google has quietly launched its own full-length online magazine, the U.K.-based Think Quarterly, a -- yep, you guessed it -- quarterly publication with the goal of "breathing space in a busy world." The first issue proves to be a 68-page dive into the world of data and its impact on business. (Mashable)

    • According to TechCrunch and ComScore, MySpace's traffic decline is accelerating. Between January and February 2011, worldwide unique visitors to MySpace dropped by 14.4% from 73 million visitors to 63 million visitors, half the audience they had a year ago. (TechCrunch)

    • Windows Phone 7 owners, rejoice! Thanks to an update rolling out to users this week, you may now copy and paste like the rest of us smartphone users. (Digital Trends)

    • Looking to wiggle out of that T-Mobile contract before the carrier gets snatched up by AT&T? You're definitely not alone. (Fortune)
