Software Development: 80-20 principle or edge case

Few days back I was reading an article of David S. Platt on MSDN. David was taking about something like 80-20 principle. As per his writing, we can make happy 99 people but not the 100th person. In his first article in MSDN he stated a feature (designed for 110th user but not for another 99 users) to dock the file menu bar as bug.

In his second article, getting some arguments against his first article, he reiterated again about the point edge cases where only a few people will be benefitted. These two articles are must-read for people who is working in management as well as for developers.
