Its come to my attention that a recent modification to the readmore handling code hasnt been sufficiently well advertised. You can now add a "title" text to your readmore tags:
<readmore title="Yada-Yada">...</readmore>
Unclosed readmore tags are considered to bracket all content to the end of the node, and a node may have multiple readmore sections. Readmore tags cannot be nested and are PM specific "pseudo-html". When the node is viewed in expanded view then the tags are converted to <div class='readmore'>...</div> tags so with a bit of custom CSS you can see what text they cover.
BTW, you may want to view this node from Perl Monks Discussion to see the readmore tags in action.
