Indexu is a general purpose directory script. If you're familiar with web directory like Google Directory (http://dir.google.com), then you may use Indexu to create such website. But this is just the basic idea. For more advance use, you may create a niche directory such as camping directory, web host directory, directory of directory, and anything as long as the content is classified into categories. Not only that, with integration of payment system you can earn money by charging for a listing fee, which ever it's basic listing, premium listing, or sponsored listing.
