    “尽管手机行业热衷于复制Web2.0在互联网上的成功模式,但把Web2.0直接移植到手机上是行不通的。”专家认为。
    “当心简单地模仿PC的服务模式,”Symbian(四班)公司研究部门的执行副总裁大卫.伍德说。“有些模式是不能运用到手机上的。”他周三在伦敦举行的Symbian智能手机展上发言。
    伍德等人认为,手机和网络的先天性限制意味着在不对这些限制进行改进之前,Web2.0模式并不能行之有效。Web2.0描绘了一个新的Web方式的产生,众多Web2.0的应用增强了用户自发生成内容或聚合更多渠道来源的数据的情况。
    他以Google地图为例,Google地图起初是为PC应用开发的。因为该项应用创始于荷兰的阿贾克斯,就象众多其他Web2.0服务一样,Google地图把数据发送到应用客户端以加快用户请求速度。但在手机上,这个发送过程将耗尽手机电池的寿命,占满手机有限的内存空间和可能产生极高的数据处理接入费。Google公司已经推出一种新的专为手机设计并力图消除上述某些问题的应用程序版本以改善手机用户的使用体验。
    许多Web2.0公司在手机终端上调整他们的服务所能采取的一种类似方法是依靠更少的基于浏览器的应用程序和更多使用小软件的客户端,这使用户能将应用程序方便地下载到手机上。“浏览器是隐藏在后台的。”伍德说。
    ShoZu为我们提供了一个为手机用户提供专业设计服务的范例,他们聘请某个手机使用者帮助用户将照片或者视频上传到网站上,用户也可以使用ShoZu管理他们的Flickr页面,比如通过手机添加对图片的评论内容。
    Andy Tiller是ShoZu创意公司的CTO,他对比性地分别用Flickr和ShoZu程序从手机把一条图片评论增加到某个Flickr页面上。通过Flickr客户端用了165秒,占用了71.4KB的数据容量;而通过ShoZu客户端,却只用了16秒和占用3.25KB数据容量。
    Tiller找到了某种便于下载的客户端模式。“下载客户端是一个巨大的瓶颈。”他说,“智能手机用户大都不愿意下载新的应用程序,即使他们的确想下载新程序。如果大部分手机Web2.0公司离不开客户端的话,那么他们的用户很快就得面临如何管理大量应用程序的问题。”
    “但现在,ShoZu将是他们的最佳选择。”Tiller说,“如果浏览器与网络得到进一步改善,我想我们将很乐意为用户提供我们的客户端的行动付诸实施。”他说。
    伍德希望看到进入手机市场的Web2.0公司越来越关注此事,部分原因是网上的用户市场争夺异常激烈。但他警告说,应用程序开发商不要乐观地认为智能手机只是“PC的一个简化版”。
    手机已经是开发商可利用的重要产品,比如提高把有用的信息加到指定数据库的内容中的能力。此外,由于人们更倾向于去任何地方都带着手机,有照相功能的手机会“令人欣喜”,伍德认为。

Experts: Don’t try to copy Web 2.0 directly to phones
Nancy Gohring, IDG News Service, Dublin Bureau
Although the mobile industry is keen to duplicate the success of Web 2.0 applications on the Internet, the wholesale transfer of that new approach over to the mobile world won’t work, experts said.
“Beware of naive copying of PC services,” said David Wood, executive vice president of research for Symbian Ltd. “Some don’t translate.” He was speaking Wednesday at the Symbian Smartphone Show in London.
Wood and others said that the inherent constraints of mobile phones and networks mean that many Web 2.0 services won’t work well without some changes to accommodate those limitations. Web 2.0 describes a new generation of Web sites, many that enable user-generated content or combine data from various sources.
He used the example of Google Maps, an application initially designed for the PC. Because the application is built on Ajax, like many other Web 2.0 services, it pushes data out to the client device in order to speed up future user requests. On a mobile phone, that process drains battery life, eats up limited memory and results in potentially very high data-access charges. Google Inc. has introduced a version of the program designed for mobile phones that eliminates some of that overhead, improving the mobile user experience.
One way that Web 2.0 companies can similarly adjust their services for mobile devices is by relying less on browser-based applications and more on small software clients that users can download onto their phones. “The browser will fade into the background,” said Wood.
ShoZu is an example of a service specifically designed for mobile users that employs a client on phones to help users upload photos and videos to the Web. Customers can also use ShoZu to manage their Flickr pages, by adding comments to photos via their phones, for example.
Andy Tiller, chief technology officer at ShoZu creator Cognima Ltd., compared using Flickr’s mobile site with using ShoZu to add a comment to a photo on a Flickr page. Via the Flickr site, he spent 165 seconds and used 71.4k bits of data compared to 16 seconds and 3.25k bits of data on the ShoZu client.
Tiller acknowledged a down side to the client model. “****ing a client is a huge barrier,” he said. Smartphone users have largely been reluctant to download new applications and even if they do decide to download new programs, they could soon be faced with managing a large number of applications if most mobile Web 2.0 companies rely on clients.
But right now, it’s the best option, Tiller said. “If the browser and networks get better, I think we’d all be delighted to throw our clients into the bin,” he said.
Wood expects to see growing interest from Web 2.0 companies in the mobile space, in part due to “intense competition” for users on the Web. But he warned application developers not to regard the smartphone as “an impoverished version of the PC.”
The phone has a number of upsides that developers can take advantage of, such as the ability to add useful information to content like location data. In addition, because people tend to carry their phones with them almost everywhere, the phone, with a camera, is available “at the point of inspiration,” Wood said.
