voting api

我的評估是這樣子...因為整合的功能都做好了
包含自動推到首頁上的機制（可能是到達一定分數後）
To be able to automatically promote story links that have a specified
number of votes to the front page you also need to install:
* Actions http://drupal.org/project/actions
* Voting Actions http://drupal.org/node/46895

還有文章、分數呈現的機制也用views整理好
* Views http://drupal.org/project/views

近期推薦文章也有演算法來解決
* Content Recommedation Engine http://drupal.org/project/cre (Use query type "VotingAPI Point System Query")
