Ya gotta remember that the web interface is just one possible implementation of a PerlMonks client. There are several other clients out there, and frankly it's just not that hard to write a new one. I myself just wrote one that displays a continuously* updated listed of new nodes. Old ones scroll off the top (with a scroll-back buffer, of course). With such a client, your concern becomes moot.

* More like continually. It polls at proper intervals, and doesn't ask for more than it needs.
