I admit to loosely using the "mobile clients are specialist browsers" line of thinking here. Facebook definitely uses links and HTTP.

Facebook mobile clients don't use the Internet?

The web is not the same as the Internet, though. The web is an open platform built on open protocols on top of the Internet.

Interesting question: What is the Web? HTTP, or HTTP+HTML? Facebook mobile clients use HTTP, so are they using the web?

Huh, this Wikipedia site is pretty nifty, I didn't know I could look stuff up on it, thanks!

So.... Does the Facebook mobile client count as using the web?

By the definition, yes, though I can't say how FB themselves count it.

I think they are coming from the web vs native app frame.

It's still over the internet, right?

Of course, but web ≠ internet.

Probably closer to a Venn diagram where the internet encompasses the web and more. SMTP, FTP etc. Splitting hairs now

It looks like mobile-only is 44% of FB use (FB doesn't distinguish between app vs. Internet), and 87% of FB users are on mobile.
