You are all welcome, and encouraged to post here. To do that all you need to do is to send me an e-mail saying just that. I will then add your address and google will send you an invitation to be an author. Just follow the simple instructions and away you go.
Postings to the blog should be relevant to the class but the blog is specifically designed to be a place where you don't need to worry about how relevant your post is. (I give you 'Basket full of puppies' as an example). I will be posting lots of things that I read in the news or that I take out of lecture (for time purposes) but that some of you may find interesting. By putting it here you can look at it at your leisure and you know it won't be on the exam.
I try to post every day when the class is running and, where possible, the postings are relevant to the current topics we are covering in class. You can access older postings (there are over 850 (!) of them from the previous times I have taught this class) by using the 'Labels' (scroll down and they'll be on the right hand side) to pull up posts on particular topics.
