I'd like to thank Kevin, who wrote in with this comment:
Found your blog from the article. Just thought you'd like to know that our corportate web filtering software classified your site, http://www.johnsample.com/ as - get this - pornography! :) maybe they thought the article on 1's & 0's was way too edgy...
I don't even know what to say.
I can't imagine what made the filtering software classify it this way.
I guess nobody will be reading my site from any libraries.
