Bahasa Indonesia or English?

Seriously, I'm still in a doubt about the language that I'll use. Honestly, I prefer English so people outside Indonesia can read my post. But, someone insisted me to post in Bahasa..

First post on my new blog

This is my first blog. I don't have any experience in making a blog or others before, so I don't think it will be going well. :p My blog will be filled with my post about my experience and my life and maybe with my favourite things. See ya' there! ;)
