If you want to have a sidebar with the last 24 hours' worth of Newest Nodes, you might want to consider installing my PMNN sidebar.

It's small, is refreshed reasonably often (about every ten minutes or so), and the more people who use it instead of pounding on Newest Nodes, the less the load on Perlmonks servers. At the current time, the load this represents on my server is below the radar, so feel free to use it.
