Post History

Novice on writing here, except few academic reports.

I've got an idea to write a blog about my travel experiences, Although I speak Queen's English, I wish to write this blog for anyone interested in the world. US English being more commonly used, since Hollywood and Microsoft/Google powered devices (and many other US based entitles) and the internet, I'm worried if I used my native tongue to write my blog. We have many weird phrases and words only handful of people will get.

How should I write my blog? Should I choose US English or my native UK English? 

And when I write, should I choose simple words whenever possible, or use some fancy wordings?(which helps me to express what I have to say, rather than using simplest word possible)
