www.gbtags.com试用的一些想法
觉得理念挺好的，是一个专门属于前端的community。好的地方就不多说了吧，我就提存在的一些问题、以及个人建议：
1、文章发布、评论没有提供markdown的编辑器
2、许多页面加载以及滚动的时候均存在比较严重的延迟，甚至卡死，http://www.gbtags.com/gb/rtcollabration/2933.htm页面完全无法加载（chrome挂了）。建议：
（1）取消部分animation，比如http://www.gbtags.com/gb/explore.htm和http://www.gbtags.com/gb/users.htm载入的时候由于<article>部分的animation过多，会造成很严重的延迟
（2）就http://www.gbtags.com/gb/explore.htm来看，页面脚本占了生成代码将近1/2的分量，没有经过uglify压缩。建议压缩脚本
3、标签没有搜索功能？
4、比较细节的一些地方：功能和设计其实很够用，很丰富，但是总觉得有些冗余。比如http://www.gbtags.com/gb/explore.htm中，比如我选择了以文本方式阅读，结果出来的就只是标题和“阅读全文”。这只是其中一个例子吧，我在设计上不是太符合一致性设计的原则，感觉稍乱了。

以上的测试是在Chrome 29.0.1534.0和Firefox 23下面简单地测试了一下。
