As you can see my blog is now up and running. I'm afraid that I didn't spend too long comparing and contrasting blogging tools. I took the lazy option and set up on Blogger as I already have a Google account (so not another link / username / password to remember). I am also a little familiar with the interface as we use this for our library blog. Of course the most difficult bit was choosing the layout and theme - redecoration may occur from time to time.
I have added in some gadgets/widgets so that everyone can share my musings as much as they like. You can also post a comment - though I am moderating these. I guess the blog will develop as I learn more on the course.
