This thread was prompted by a comment by @Procrustus in another area:
I heartily endorse this suggestion. There are a few posters (you know who you are) who routinely only post a link that shows up as a headline and a couple of lines of text. They probably think the relevance/importance/salience of the link is apparent, but it isn’t always. I’d like them to call specific attention to what strikes them as worth noting about that article. A couple of pull-quote lines would be helpful, too, especially because sometimes the preview cuts off a sentence in the middle.
