Ok so I have a Blog...What now??

Welcome to my first ever post on my first ever blog!
I figured I must be the only person on the planet without one so I had better join in. So now I have a blog, what exactly do I do with it? As far as I understand the idea is to write about all the amazingly exciting things that happen in your life, then thousands of people subscribe and want to read all about you in a similar way to reality TV but I get to control the content?!?!
Anyway until I work out the exact reason for wanting complete strangers to know all about you I will try and post some interesting and informative ramblings mostly about my photography work and my life living in Hong Kong, China.
