Imagine you are a woman at a party who spots a good-looking fellow standing alone in a corner. Before working up the courage to
talk to him, you whip out your mobile phone. A few clicks reveal his
age and profession, links to his latest blog posts and an amount of other personal information. To many, this sounds like a nightmare. But to those building so-called “mobile” social networks,
it is heaven; linking virtual communities such as Facebook or MySpace
with the real world. The idea is not new, but so far
such services have not gained much traction. They have to be able to
pinpoint people in order to work, but satellite positioning does
not work indoors. More importantly, it is hard for such a service to
gain critical mass: why join, if it does not already have many users?
A new generation of mobile social networks may have found ways to overcome these barriers. One is Aka-Aki, a start-up based in Berlin. Users of its service download a small program onto their mobile phone.The software then uses Bluetooth, the short- range radio technology built into many mobile phones, to check whether any friends or other members with similar interests are within
20 metres. If so, the program pulls down the person’s picture and
whatever information he or she is willing to reveal from the firm’s website.
This works because each Bluetooth radio chip has a unique identifying code that can be used to look up a person’s information. To overcome the chicken-and-egg problem, Aka-aki is also a web-based social network with a twist: to express their interests, members can create virtual stickers and share then with others, which then makes mobile matching easier.
If mobile
social networks do take off, they are likely to do so first in Europe,
rather than tech-happy California or mobile-crazy Japan.This is, perhaps surprisingly, thanks to regulators. European operators are required to keep mobile phones more open to software downloads, with the result that they can run programs such as Aka-Aki’s. (Google is pushing for more open handsets based on its new Android platform, but the first phones will not appear until the second half of 2008.) Many mobile phones in Europe also come with Bluetooth, because drivers there need it for their wireless headsets: talking directly on a mobile phone while driving will earn you a hefty fine in most countries.
想象一下你是个女人，在聚会上看到一个帅气的小伙子独自站在角落里，在鼓足勇气去跟他打招呼之前，你拿出自己的手机，摁几下键盘，手机屏幕上便显示出他的年龄和职业，并链接到他最新的博客上，还显示出他许多其他的个人信息。对于很多人来说，这听起来像是一场噩梦。但是对于那些靠手机来建立社交圈的人来说，这就像是天堂一样，因为它可以将Facebook和MySpace这样的虚拟空间与现实连接到了一起。这已经不是新点子了，但是这样的服务目前却还没有得到推广。因为这样的技术需要精确定位人的位置，而且目前卫星的定位系统还不能在室内运行。更重要的是，这样的服务很难得到大多数人的认可：如果没有广大的用户群，为什么还要加入呢？
新一代的手机社交网络已经找到克服这些阻碍的方法。其中之一是Aka-Aki，一个在柏林新建立的公司。该公司的用户下载一个小小的程序到自己的手机上，这个软件可以通过蓝牙，即手机上的短程无线通讯技术，去检测我们周围20米内有没有和我们兴趣相投的朋友。如果有，这个程序会把那个人的照片和其他任何他（她）愿意公布在该公司网站的信息发给你。
这个过程可以实现是因为每一个蓝牙无线电芯片都有一个独一无二的认证码，可以用来搜寻一个人的信息。为了避免所谓的“鸡生蛋还是蛋生鸡”的问题，Aka-Aki公司的这个软件在大多数手机上都可以运行，并且为了推广还提供会员间免费短信的服务。此外，Aka-Aki是一种社交网络平台，会员可以说出他们的兴趣，并且粘贴很多相关的资料与他人共享，同时可以使手机交友更加便捷。
如果这种手机社交网络真的能够推广，那也是先在欧洲，而不是在科技发达的加利福尼亚或者是手机发达的日本。这或许得益于规定，因为欧洲的运营商允许手机下载各种软件，这样用户就可以在手机上运行诸如Aka-Aki这样的程序了。（Google正在大力推广能够支持它Android操作平台的手机，但第一批手机知道2008年下半年才能温室。）欧洲的许多手机都有蓝牙功能，因为司机在开车时需要用到无线耳机，在许多国家，如果直接接电话将面临很高的罚款。
