This is absolutely true and for me, it was a real shocker. I developed an extension called Better History. Before the redesign, I had 500 active users.
On the day of the redesign, installs skyrocketed. Everyday since has seen a 2,000 to 3,000 user increase. At the moment it's up to 11,000.
I did prepare some promotions that I think really helped get Better History some face time.
