Blogging

Oh Wow, this is all very new to me, I've never really thought about writting a blog.. just read others and criticised from afar. However I am now in the position where I have to write one for my course (Advertising with Marketing Communications) so I thought I would get started before being given my first assignmnt. In all honesty I'm not finding much enjoyment in this whole 'New Post' malachy, how are you supposed to know what to write? Atleast next week I'll be given something to write..
I always wonder about how people read things that I write. Like, texts or emails or IM's and now this. If they know me does that mean they read it in a voice like mine? The way I write can often mean entirely different things if read wrong, so I tend to take extra care when reading things written by others. Even if I don't know the person. I tend to make assumptions about how they would speak, gathering clues from the style of their language; the way they spell, their punctuation... In that case I wonder what assumptions would be made about me??
I tend to be a huge fan of exclamation marks, (I've held back seeing as this is my first post, don't want to scare anyone) I just like the way they look and what they imply. Things just seem more exiting with a '!' after them, even the dullest of sentences (or posts)!
