Hmm. We should have UMA stats around this tutorial: When it's Shown and when
people Acknowledge it. Similar to Profile.NewAvatarMenu.NotYou/Upgrade/Signin

Not that I'm against that but how actionable/insight-providing would those stats
be?

We've already decided to require that the user dismiss the tutorial manually so
the data would show #times shown/#times dismissed (basically the amount of times
people see it before they get that they need to dismiss). That would probably be
interesting insight but I'm wondering if it's worth the additional metric
considering it doesn't lead to any follow up. Do you have anything else in mind
that I'm not thinking about?
