Hi Robert

>From the `WHERE` clause here:
https://github.com/wikimedia/analytics-refinery-source/blob/master/refinery-job/src/main/scala/org/wikimedia/analytics/refinery/job/ClickstreamBuilder.scala#L283
you can see that we bundloe altogether desktop, mobile-web and mobile-app
rows.

As for the reason of so many empty referrers, I don't know myself, but I
know it's been a topic already discussed.
IIRC Nuria and Jon Katz looked into it a bit, and more recently Isaac
Johnson (all in direct copy).

Cheers
Joseph
