There can be (though you’d be surprised- there’s rarely such a thing as a non-identifiable user nowadays). Just pointing out it’s a very big conditional.

For example: I work at Bleacher Report and our non-logged-in users get data customized for them. That can be as simple as GeoIP data or can be us knowing (and inferring) what articles or content they’ve seen.

The permutations are quite large.

Now some blog, or a very simple app won’t do something like that (hell, they might not have the depth of content to be able to) but it’s reasonbly common to have that requirement on large sites outside of v.limited pages (like login/signup etc)
