You can use the Mechanize gem to fetch one or more pages from a site and 
then compare it to a saved version to detect changes. If the page has a 
time/date stamp, it won't match exactly so you'll probably want to 
figure out some way to monitor the parts of the page that matter to you. 
Regular expressions will be your friend here.
