Maybe I'm in the minority, but I haven't ever used WhatsApp. Is there a huge benefit to using it over SMS, or something similar?

Yes, they do. iPhones don't seem to do that, but old GSM phones did it (like my first phone, Ericsson T20, which got released in 2000). Androids have read reports in the default message app, if I'm not mistaken.
I suspect a fairly small percentage of users is active enough that you get usable hourly data.
It's certainly a more popular app outside of the USA. They initially gained traction because they were willing to make apps for things other than iphones and androids - which gave them a huge following in the developing world where people may still use 10+ year old candy bars.

Wait, when you view her profile (as a friend), it shows who has the highest 'score' in terms of contact with her? Wow, that IS a lot of data if they break it down by contact pairs.
Yep. It was called Snapchat score or something. It had a list of top 3 people or so and how much score they had with each other. It was unreal. This was back in spring-summer 2015.
Wth people?
A few weeks ago there was a similar discussion, and I commented the following: If you think there is no problem, you are wrong. The blog post does not show all the information leaks that this implies. Example: I can modify the script to monitor all the numbers I've in my phone, so that based on the online/offline status in a few weeks I can be able to guess who is having conversations together, discovering cheatings,…
Even if you don’t set away states, one can simply monitor every channel you’re in, every message you send, and then quickly determine what timezone you’re in, when you sleep, when you’re on vacation, etc.
Here’s an example graph of a user, every dot is a message: https://i.imgur.com/DrgVvVw.png and here one from a user with more regular sleep patterns: https://i.imgur.com/a1xdSqR.png (notice the timezone transition when daylight savings time starts? And notice how the user takes about 2 weeks to adjust?)

I agree with you, whatsapp is not like Tinder or Facebook you don't open it every 2 minutes to check if there is something new.
I live in Colombia, before then Mexico, and yes you do check on it every 2 minutes everyone does, at least in Latin America

This isn’t just necessarily a problem with WhatsApp. The same applies to IRC, if you set away states.

Anyhow, I'd disable showing online status, typing status, or automatically changing status based on activity.
This was a decade and a half ago, probably longer. The principle remains the same. No, no I don't want you to know when I'm in front of my computer, typing, or otherwise. If I want to appear online, I'll manually do so.

Most Tor busts follow a similar pattern, watching both ends of the connection. There is a real need for a "tor delay" metadata-disruption-as-a-service, where random strangers invoke one another's web callbacks and report back the result in exchange for Bitcoin (Strangers on a Train -style). Someone put it on the block chain and start an ICO!
