I used to find blogs a little odd, as there is a presumption that someone else will find your thoughts interesting but a friend of mine, Kate Andrews, has inspired me to revaluate this. For example, a blog can help you to define what you are thinking and keep track of conclusions that you make. It can also open your thoughts up to other people so that they can (constructively) criticise them and help you to share things that you think will help other people.
I suppose as my first ever post I should think about what my aims are:
To attempt to make a conclusion at the end of every post as I have a bad habit of only asking questions.
To add some thoughts of my own and not just distribute news.
Only to post when I have something important to say (this will undoubtedly keep the blog very short indeed).
