Show HN: A Site for Understanding Open Source Projects (early prototype)

There's been lots of discussion recently about Open Source projects and their possible lack of documentation.

We have an early prototype - see here for an example for the results of Lucene:

http://www.codemaps.org/s/Lucene

Now, putting content on such a site has challenges, but we are wondering what you think of the output of such a site.

If you use Lucene: Is the site helpful for you? Would you like something else on such a site?

If you use other Open Source projects: Would you like to see something like this for your project?

I hope you like it and find it useful. Really looking forward to hearing how you would want it improved.
