I am amazed at how many people read this blog

Google, the owner of Blogger, has this option where you can see general information on how much people read your blog.  It's nothing super specific, just things like the general location of visitors and the amount of time they spend actively reading the site.  What amazes me is how much time people spend reading my blog.  In the past month people from the United States collectively spent more than 11 hours and 30 minutes reading my blog.  Canada spent over 1 hour, Australia 10 minutes and France 5 minutes.   Can that be right?  What could be that compelling?  I strongly suspect that Google statistics are just BS, but who knows.
