You have some options on following this blog:
Email notifications: you can set up email notifications for every new post. To do this, go to the Blogs I Follow page when logged into wordpress.com and edit the notification settings for our blog.
RSS reader: this is a great option to keep up not just with our blog, but also with other blogs and newsfeeds about topics related to our class, and in general (see the links on my course page). Some RSS readers that are free and work directly in your browser (no need to install any software) are discussed here.
