Compute the social call graph: Find who wrote the code that calls your code. Find who wrote the code that your code calls.

Learn who cloned your code, and keep them up to date on changes to the original.

Discover how difficult your code is to use. Write better documentation to cover how it is actually being used.May 20, 2009 8ICSE NIER 2009
