Known Good Software
Good software is not only a pleasure to use, but is well written. Unfortunately most software is rarely a pleasure to use, let alone well written.
Window Managers

Programming Languages
To what degree we should ignore the underlying execution of the code and in what way is unclear. Therefore languages such as Haskell cannot be considered good software at the present time.

- Go
