libgit2 is a portable, pure C implementation of the Git core methods provided as a re-entrant linkable library with a solid API, allowing you to write native speed custom Git applications in any language which supports C bindings.
GitHub has continued the libgit2 Google Summer of Code effort, supporting Vicent Marti to continue the development
Scott says that Git is basically a key value store and we should look at uses beyond version control
Eclipse is moving to Git away from CVS
Git Tower is a beautiful Git UI for the Mac

Jason J Williams’s tools have lessened the pain for Wynn in writing the upcoming Sass book for Manning
