Outdated section | 'What to do next' -> 'Test for Graceful Degradation'

[HelloThisIsFlo]

Hi,

The section: 'What to do next' -> 'Test for Graceful Degradation' mentions Persona.

At first, I figured I missed something somewhere but after a quick google search I realized it was a leftover from the first edition

Solution could as simple as removing the section.
