So if 95% of traffic/users/whatever metric are not using a web browser for those activities, is it really the web? It can't be called the web just 'cause they use HTTPS. It's gotta be a 'world wide web' experience, which I think a good proxy for would be using a web browser.
I got no horse in this race, just thinking out loud about it.
Another common phenomenon these days is that lots of businesses don’t even bother having a web presence - it’s all instagram, WhatsApp and tiktok accounts, mostly only accessible via apps (or worse, chat platforms like discord)
Agree YouTube and Instagram are probably mostly apps which puts them in the “Internet” category but not “world wide web”.
There are several meaningful difference between surfing Youtube and surfing the web. These include ownership, access, review, exposure, and more.
Honestly the web died long ago imo. Wikipedia and other wikis are the only places that feel like the old web to me now.
