Raises an interesting point.

How large does the canvas need to get before pagination makes sense?

Modern websites are enormous in terms of how much needs to be loaded into memory- sure, not all of it is part of the rendered document, but is there a limit to the canvas size?

I'm thinking you could probably get 100,000+ entries and still be able to use CTRL+F on the site in a responsive way since even at 100,000+ entries you're still only about 10% of Facebooks "wall" application page. (Without additional "infinite scroll" entries)
