An Internet Hoax

Below is the link to an online hoax that I randomly came across recently and thought was relevant to this week's reading on credibility. Apparently the page's creator was a college professor trying to teach his students that you ctan't always trust information you come across on the internet. Also interesting is that it's an example of rather poor design and usability, which we're learning are predictors of perceived credibility. It hasn't stopped some for beliving the site, though.

Have you come across any other examples of outright hoaxes or pages that appear less than credible? How do you determine credibility when doing research? When using the net for personal use?
