If you look at the bottom on the right hand column you will see a link to Mapstats. This is a free way of keeping stats on the (depressingly low) readership of this, or any, blog. The cool think about this (apart from it being free) is that it also maps the usage so I can see where usage is coming from and which specific post is being read. As a visual person anyway, I am increasingly interested in the various spatial ways we can display data, interactively and in real time.
You can see my readers are all in the US, not even my mother reads it!
