After being mostly (ok, entirely) inactive since around January, I checked Newest Nodes and received a(n extremely) long list of 'New' nodes since my last checked flag from ~2008-01-18. While it's certainly an edge case (and easily dealt with, at that), perhaps it would be worth the effort to only display a few of the more recent nodes if it looks like the returned list is going to be very (very) long. The rest could be displayed if that is truly the user's intent. Or these flags could be cleared after some time (probably suboptimal), or something else, or nothing at all..
