For anyone who doesn't yet know what Newznab is; it's essentially web server software, written in php, that allows anyone to run a newsgroups indexing site, with relative ease. It indexes newsgroups content automatically (no human intervention necessary), determining post titles and creating NZBs (it can even create thumbnail images, if configured to do so, for some content automatically). Some people are using it to build new public newsgroups indexing websites (hence the multitude of new, similar-looking indexing sites appearing recently), while many are using it to build their own private (Intranet/LAN-based) indexing servers.
