If someone clicks Learn More, does the card disappear.  If not, when the user
returns to the card and clicks something else, does it get recorded?

[pedro (no code reviews), 2014/02/14 18:29:18]

Good question. When the user clicks on the "learn more" we'll open a new tab in
the foreground. The card will not disappear per se, but it won't be visible (a
new tab will open on top of it). After closing the "learn more" tab, the user
will see the Opt Card again and will have to perform an action to make the card
"disappear" (he will have to choose to opt-in, opt-out, or close the opt card)
and this action will be recorded.

If I take a bunch of times, all of which are ignored or invalid, are these all
logged, is just the first tap action taken after opting in recorded?

[pedro (no code reviews), 2014/02/14 18:29:18]

All taps will be logged, not just the first one.
