Steps to reproduce:
1. Visit http://lybio.net/john-stossel-some-people-shouldnt-vote/people/
2. Click SENDtoREADER bookmarklet.
When this arrives on my Kindle, it shows some HTTP messages, the title of the article, and that's it.
But when I manually select just the article text and click the bookmarklet, it works fine.
I am using Safari 5.1.2, Mac OS X 10.6.8, and Kindle Keyboard 3.3 (611680021)
