How Facebook did UX testing for Home

Interesting piece on how Facebook did UX testing for their new Home software. Some of the more interesting bits include:

• Did most of the testing on Facebook employees (non-design or development)
• Utilized diary testing to find out about long-term effects of content (initial reaction is often positive, wanted to see how people liked it over time)
• Testing priority was on first-time user experience
• Live stream testing that anybody can view in real-time
• Send out a weekly email to the team with highlights of testing
