A weak requirement might be written as: "A user is able to easily publish an article with one click of a button." This simple sentence implies the interaction (one click), the interface (a button), and introduces an ambiguous measurement of quality (easily).
As an example, I once had a client ask for a "homepage made of buttons, not just text." He had no idea that, to a web designer, a button is the way a user submits a form online. To my client, the word button meant he could change the content over time as his business changes.
