Opening the App Store to download a bunch of apps - in general - is probably the #1 thing people are doing when they open the App Store. Of course, installing a specific app is a top use case. But I think you're just not the average user. Lots of people open the App Store frequently to just check out what's available.
~10 years ago I would do this all the time. It's fun, kind of like surfin' the net was back in the old days, but in a walled garden of applications.
