The other day I calculated my net contribution to the IMVU client, in lines of code. Excluding third-party libraries, I have subtracted about 100,000 lines since 2005.

Reminds me of an old presentation by Alan Kay. He was demoing some networked virtual world he'd written, including avatars, portals, and chat. He wrote it in Smalltalk, and said it summed to 60,000 lines. He said with a bit more effort, he could probably reduce it to 20,000.

There's something to be said for a complete lack of duplication in the system.
