It's not as user-friendly as blogger. So I cancelled the domain mapping and the premium service and I will be refunded. But it takes some time, for them to un-map my domain, so I can't do anything right now. Oh well, at least I tried.
Yeah, Blogger isn't perfect, but what do you expect when it is FREE. They have many more options than WordPress and if you want more, on WP, you have to pay.
Free is a very good option!
