The WhoisLike.it homepage is so sparse that it makes Google's home page look crowded. But it couldn't be easier to use. Just type in the URL of a web site you like, and WhoisLike.it will analyze the content and spit out a list of sites that seem to have similar content. Each site features a screen shot to boot.
It's not quite clear how WhoisLike.it determines which sites are similar. It could be checking for incoming and outbound links, or the service could be looking for keywords and comparing a site with other pages in its database. But it does appear to work pretty well. While you certainly won't find every similar page on the web this way, WhoisLike.it will probably turn you on to a few interesting sites you may not have seen before.
