Yeah, I've worked at places with millions of users and product managers are drowning in data. It honestly doesn't really make it much easier to build features that actually drive revenue. To a large extent, this is why advertising (and related data selling) is so widespread: because it is obvious how to make money from the data. Someone said they'll give you $1,000 for a list of all the users who are male, in Canada, and have typed in stuff about Python. The parent's example about tag hierarchies... That sounds like exactly the kind of nifty feature I've seen launch a dozen times that has precisely zero impact on revenue.
