Appolicious:手机应用搜索引擎是一个手机应用（iPhone/Touch）分享社区，你可以分享自己的iPhone/Touch应用，分享自己的手机应用列表，给手机应用写评论，评级，下载免费的手机应用软件等等。

用户注册之后首先需要选择自己的手机设备（iPhone 3G、iPhone 3Gs、iPod Touch、iPod Touch 2G、Original iPhone），选择自己感兴趣的应用类型，此外Appolicious的独到之处是引入了Follow机制，和传统的SNS网站的好友机制不同，用户可以选择Follow用户来了解他人分享的应用软件，同时用户也有Block自己的Follow者的权利。

这样一来，手机软件的评分也有三种:一种是整站用户的评级得分；一种是你Follow的用户的评级得分；还有就是Follow你的用户对此软件的评分。个人觉得如果自己的Follow的群体是一个可信赖的人群，那么自己Follow的用户群的评分应该比整站评分更有价值。

Appolicious就是一个很好的将手机软件应用和Twitter的这种Follow相结合的一个网络社区，对于传统的分享社区而言，一直都是采用好友的机制（即相互加为好友），而对于类似于软件分享而言，其实很多人也都希望了解更多的用户的使用情况（很多情况下并非自己的朋友），这样一来这种Follow就大有用武之地了，并且加入这样一种机制之后，对于软件的评级数据也有了更多可以挖掘的信息。
