Experience of Hatena Diary Plus

I began to try Hatena Diary Plus a several days ago. My article layout is sometimes corrupted, but I have no idea about the reason. Just thought advertise banner makes my article layout broken, so trying Hatena Diary Plus and disabling advertise banner can make this layout corrupted resolved. But,,, nothing has been changed by disabling advertisement banner.
My assumption was not correct, but I found the root cause. The root cause is linking keywords function. This function sometimes corrupts the blog layout. Disabling this function completely required Hatena Diary Plus. If not using Hatena Diary Plus, it is possible to mitigate linking keywords. After finished my free experience period of Hatena Diary Plus, I am going to check my blog articles again. If linking keywords function would broke my blog layout, I may keep Hatena Diary Plus....
