My own use of the style revealed a few issues with long titles that motivated an update: ollicle_nnw.css. This version also included a maximum width on the news item description to prevent uncomfortable lengths of hard to read text.
I made a few more little changes to this style up until the release of the beta of NetNewsWire 2.
