Selects the headlines on the front page of http://www.smh.com.au/, avoiding most of the stuff that I don’t want to read.
Unfortunately, this does not include the main articles on the category pages, because they use the same jQuery selector (div.wof>h3>a) as many of the things I want to avoid on the main page.
This works reasonably well for me:
div.cN-storyHeadlineLead:not(.storyRHS)>h3>a, ul.cT-wireNews>li>a, ul.featuredStoriesList>li>a, div.wof>p>a, h3.cN-storyHeadlineOnly>a
