Where are the semantic web applications?

With Facebook causing lots of websites publish RDFa, I would expect to see
some interesting semantic web applications (i.e. ones that consume linked
data, such as http://data.nytimes.com/schools/schools.html). I'm constantly
monitoring the web for these application, but haven't run into ones yet
(except those which display as HTML the RDFa that was in a web page).

 

Any thought on why that is or where I could find them?
