Google have upgraded their "mini link" to be less mini.
This comes days after Matt Cutts (video link) downplayed the importance of keywords in URLs. I think these expanded mini links - which show off the URLs - put in a strong reason to have search engine friendly URLs. If the green link text have keywords then users are more likely to click.
Speaking of which. I think these mini links will have an impact on PPC. In the Danny Sullivan example above the PPC links for his books now have much stronger competition from the organic results. Click through ratios could drop. This will impact on the QS+CTR metric.
In other news, I've recently found Newsvine and am mightily impressed.
