What do people think about "minutes per day" as a metric for success? I think it represents a fundamental misalignment of goals between users and the company. By this metric, the more of your waking life that can be taken, the better.
I don't get it. It's not like users are forced to use these applications. If users like Instagram more than Snapchat, they're bound to use it longer (which the article seems to imply). Hence, the metric.
Snapchat and Instagram share some of the same purposes, but most use them for very different things. This article is Facebook trying to say "Look we beat Snapchat at another thing!" in order to leverage their network effect power. What likely happened is they optimized their app to do exactly this with the goal of this press release (and ad revenue as well likely). None of this actually speaks to the app experience of either inherently.
Despite both having app use times over 30 minutes, the reasons for each are entirely different. Instagram is because you are scrolling on a feed. Snapchat is because you're messaging people or taking pictures to send.
