> Then, as now, the "beta features" tab lists the number of users who have opted-in to a tool, but there is no comparative/objective explanation of what that actually means! For example, it tells me that 33,418 people have opted-in to "Hovercards", but is that good? How long did it take to reach that level? How many people have switched it off? What proportion of the active editorship is that? And most importantly - what relationship does this number have to whether Hovercards will 'graduate' or 'fall' the opt-in Beta process?
It would be useful for product managers (et al), to be able to track these stats over time. Ideally in the form of an [[https://en.wikipedia.org/wiki/Area_chart |area chart]].
