2.6. Fetchmail Becomes a Category Killer

• Eventually, popclient that was renamed to fetchmail in the course of its evolution became a "category killer".
• "one of those classic programs that fills its niche so competently that the alternatives are not just discarded but almost forgotten."
• Even after your software has become a category killer, there is still room for improvement, and you should still listen to your users and implement new features.
• "The number of items on a project's To-do list always grows or remains constant" (my own invention)
