I wish they showed how many people weren't using Private Browsing. For all we know the spikes might just be because more people are browsing the internet at those times (I suspect that's the lunch spike).

In the context of this discussion, percentage of Private Browsing activations would be more useful.

This is a great point, and one we should have addressed in the post.

That said, there is not generally a spike in usage at lunch for anything else. For many other metrics of interest we see a familiar sinusoidal wave of usage, with the low point at around 3 or 4am, and a high point at approximately 6-7pm.

Thus the spike in usage at lunch turns out to be quite unexpected.
