HBO’s Silicon Valley just aired ‘Daily Active Users,’ episode 9 of season 3, in which the engineers are suffering the effect of zero user research or testing (well, outside of their own circle). All the beta testers were loving Pied Piper. The lone Cassandra of the group, Monica, stated an episode or two back that she didn’t like the app (see Reddit convo on this), and that came to represent the opinions of the masses. Check out the user group in the preview.
Moral of the story? Do your research, conduct validation studies, and don’t waste money on marketing when you need improved UI and UX.
