Writing style...?

A chap I know, friend-of-a-friend, kindly agreed to read The Grim give me some feedback and possibly a review. Which is very nice of him. I greatly appreciate it.
But as we talked he mentioned that my writing style is very different from the writing style I use in this blog.

Hmm. Is it?
Actually that's not the question I asked myself. I was confused...
The question I asked myself was, 'Why would he think that they would be the same?'

The style I use when writing this blog is different to the style I use when writing a film script, and different again from the various ones I use when writing fiction, and different again from the style used when making notes, writing a letter to a friend, writing a letter to a corporation, etc, etc. ... There are going to be aspects in common, but doesn't everyone adopt a different writing style for the specific task they are engaged in?

The syle I use when blogging is, I hope, engaging - and I speak as though chatting to a friend on the internet. (?) Informal. Just a chin-wag, a bit of a natter. ... The mad ramblings of an insane mind!!!
You know the drill, surely?

Anyhow, I'm supposed to be writing, and instead, here I am procrastinating. *sigh*

I'd better get back to it.
