I just finished moving both of my Japanese blog to my own domain, katzueno.com.
I’m using WordPress for my new blog although I’m a Japanese developer of concrete5 CMS.
Every software has its advantage, like Mac and Windows. Some poor people say that Mac is better than Windows, Windows is better than Mac or Linux is better then the rest.
The smart people can use them all :p
Anyway, I can use concrete5 but I also want to take advantage of WordPress and learn from it.
