This particular blog is well past the 10,000 visitor mark now and I've had people drop by from all corners of the globe (if a globe can be said to have corners). As an example, here's today's world map representation of where this blog's last 100 visitors came from.
I have had people from South America read this blog, regularly in fact, just not in the last 100 people. However, I don't think any penguins with broadband Internet, or the scientists observing said penguins have ever paid a visit. So, if you know anyone posted to Antarctica tell them I said 'Hi!' and asked them to pop by soon and leave a message.
Thanks. Over and out.
