[uf-discuss] What social networking sites uses XFN to express relationships and makes the XFN data visible so that it can be screen-scraped?

[Costello, Roger L.]

Hi Folks,

What social networking sites use XFN to express relationship
information?  

In particular, I am seeking sites that let me see and scrape the XFN
data.  That is, I want to be able to do View Page Source and see the
rel="..." on the link.

Apparently WordPress uses XFN to express relationship information, but
the XFN data is not visible.

Thanks!
