This come from my mind depend on my use of it.
1. It's very quick, it use the cache(file cache ,memcache and datacache), you can choice which one you like.

2. It's very extensional, why say that, every model can be write in extension or component or module, very convenient.

3. It's have hight security, It have consider the code attack and sql attack, so rest your heart to use it.

4. It's easy, really. You needn't install some other software to make it work, it only needs the basic environment for php and mysql. Also the template is very agile, you can choice smarty, phptemplate or others.

5. It open source, share your mind and contribute is greate!
