This is a great plugin, but I had to disable it on my site, because it doesn't work if you come to a blog post from outside your blog.
Steps to reproduce:
1) On an iPad, search google for "ruby spell doctor" (or just click on http://www.google.com/search?q=ruby+spell+doctor)
2) Tap the result that points to the post on sandropaganotti.com
3) Try to scroll the post. The left column is scrollable, but the right column isn't. If you tap the link in the left column, you can scroll the post.
