I will Launch my English Version for this Blog

When i was stuck in searching how to tag my blog, i was thinking that is why im not change my blog language from Indonesia to English? Not just reader from Indonesia will read my posted but all the people in the world will read my post.

But i know it will spend my whole time to convert this blog to english. Or maybe i will make it two version in one blog for each language. One for Indonesia post and one for english post. Or i will make two blog with different language? What do you say? Guys need you help badly T_T
