...but in a larger shop, comments are important and helpful to the next person looking at your code...
I once worked with a woman who deliberately wrote opaque code and misleading comments as a form of job security. Nobody was able to decipher how her programs worked. She had the boss wrapped around her little finger. She convinced him that everyone who touched her code was an idiot and would make a mess.
The shame was, she was quite bright and didn't need to use these tactics.
When the company was purchased by a much larger competitor, people from the acquiring company sent their systems people to examine what they would keep and what they would discard. When her work was reviewed, she joined the unemployed queue while the others in her department were absorbed into an expanded IT centre.
