RSS/RDF is probably a good way to go.
Offer multiple RSS feeds ( take a look at COM_ExportRDF() in lib-common.php, or wait for me to get off my ass and finish my GL plugin).
Adjust the function to generate an extra feed or two: 10 most recent headlines, 25 most recent headlines, and 25 most recent with full text. (substitute 10 and 25 with whatever suits the pace of your site).---Lucas Thompson, sardu@mac,com
