(Eventful.com and upcoming.yahoo.com come to mind.) However, I'm seeing other sites where a minimal amount of information is provided (fn, photo, url to page relative to the site).  This data may be of interest from a search index perspective. However, for an application consuming Microformats, it is of less interest.

I have noticed on many social networking sites such as Twitter, 
Magnolia,  LastFM... etc  use XFN <http://gmpg.org/xfn/> to define which 
hcard's belong to who for example Twitter, Magnolia and LastFM use 
@rel=me to idenifiy the Users profile hcard and @rel=contact to mark up 
the hcards of a users er.. contacts., this pattern is found on a few 
blogs and homepages too.

There is and Demo on how all this information can be put together, you 
may find it useful in your quest take a look at 
<http://weborganics.co.uk/hFoaF/> there is also a wiki page with lots 
more examples of  hcard's supporting user profiles here: 

Best wishes
