“In my opinion, there is nothing in the programming field more despicable than an uncommented program. A programmer can be forgiven many sins and flights of fancy, including many of those listed in the sections below; however, no programmer, no matter how wise, no matter how experienced, no matter how hard-pressed for time, no matter how well-intentioned, should be forgiven an uncommented and undocumented program. “—Edward Yourdon, Techniques of program structure and design (1975)

I think the programming community is similarly moving from an era of code scarcity to code abundance. It's funny to think that a chunk of code donated to a project was a gift in times past may soon be seen as unwelcome code carcass in the post-code-scarcity days that follow.
