Shared Short Names Table

Shared Short Names Chart

This graph shows the number of short project names shared in common between each pair of projects. For instance, starfish is a project listed on both Sourceforge and Rubyforge. On Rubyforge, it is described as a "tool to make programming ridiculously easy", but on Sourceforge the starfish project is described as a password management application. There are 1367 projects with shared names on Rubyforge and Sourceforge.
