As a fellow bilingual I salute your curiosity! It's a weird world. I too write all my entries in English - hell, lately all I write is in English. That's mostly because most of my online friends are born-English speakers or bilingual like me. I have only one Italian on my flist - the others wouldn't understand a thing! In fact it was quite amusing when our Jessy was here this summer - a German and an Italian both speaking in English to each other! (but other than that, I speak my mother language IRL. Probably because next to nobody understands it here *grumble*)

It's easier. It's a language that gives you tons of options and quite the colorful expressions. And gives you the chance to make (and stay in contact with) great friends. And to chat with rockstars. XD
