Seems like "Reach" is very low, compared with number of headsets sold?

Hey guys,

I am wondering if everyone is seeing roughly what I am seeing for Reach, Unique Clicks, etc.

If there are millions of headsets, why are these numbers so low for a 28-day span?

My guesses:

• The vast majority of people are not using their headsets.
• People don't know how to search for apps.
• People aren't searching for apps. They play what they already have or spend time somewhere else.
• People search for apps, but Search has been broken for awhile, and is just now starting to work a bit.
• Something else?
