One day, I want to buy a domain for my new blog. I need it for more customize flexible blog. Yah, I already run out the customize space for my bloger.com blog. I want to learn about deep SEO technique implementation at my blogger.com blog, but it can not support. Therefore, I do some research in internet according this problem and found that WordPress engine blog support this deep SEO technique implementation. So, I decide to use WordPress engine for my new blog at that time. But, I still confuse between self hosting or just join the free WordPress.com.
