It is a pain when this happens, though it seems that nodes that have blank titles but contain content are given titles by the moderators (eg More IPC::Open2 stuff was originally untitled). If you want to read these nodes, your best bet is to find out the node ID (by reading the page source from which they are linked to...), and typing the URL directly into your browser (http://perlmonks.org/index.pl?node_id=whatever&, replacing whatever with your node ID)
