I've been trying to work out the newer google search results where you see Sitelisting for some search results - those 'sub-heading' with descriptions you see after you have done a search on something (try googling viart, you'll see what I mean)
if any of you have worked out how to get google to do this on your site, let me know.
On another point, I was looking through the WebMaster tools and Google now has 'Data Highlighter' and Structured Data option. Which I think may be related to the sitelisting options.
I've been trying to set up Page Sets under Data Highlighter, but cant seem to work out how to get the page sets to work. I think this is in the most part because everything is 'anchored' to the root directory no matter if you are in Products, Articles, or Ads.
ie I think google now expects these 'sections' of the website to have different root directories.
eg http://<yourdomain/products/{blah}
