I could swear I'd seen a selector offering to show nodes created within the last X days. It's not there for me right now, so I may just be hallucinating, again. ;-)

I would much rather have Newest Nodes show me the most recent postings (with a selectable time frame), than have it clear them out periodically. In other words, I think a "sliding window" of the latest nodes is better than "fill it up, then empty it out, then start filling it up again."

IM(not so)HO... :-)
