I'd recommend two other solutions before adding the dashed line.
1. Increase the contrast (could be lightness, saturation, size, or a combination of the those) between the link titles and preview text. Right now they are similar enough that when I scan the page, I see block, block, block... instead of link, link, link...(which is how I think it should read). If you look at Google or even Reddit, the links are bright enough that you can scan the link titles without noticing the preview text and/or meta info.
2. Increase the whitespace between each block to create more separation.
I think #1 is more important because link-scanning will still be a problem if you add whitespace or the dashed line.
In my opinion, it's best to use spacing, alignment, and contrast to separate objects before adding new objects to act as seperators.
Thx, this is why I haven't done it to date. The link colors were actually brighter, but people kept complaining about them being too bright, which is how they got to where they are now. But I'll give that another look.
Wrt to spacing, there is actually quite a bit and I get a lot of complaints about there not being enough spacing, though I made a setting for that. I'll also revisit.
