Yes.  The two I know of are reevoo, which aggregates hreviews:

http://www.reevoo.com/

and my own effort, which aggregates hcards, hcalendars, and hreviews:

http://randomchaos.com/microformats/base/

My main challenges have been a lack of space to store the data (which  
has nothing to do with microformats) and the the lack of a parser  
that can read invalid X(HT)ML (which is only an issue because I  
haven't installed Tidy on my server).  If microformat site maps  
existed, I would use them as starting points to know where to look,  
but I wouldn't trust them as any sort of accurate listing of what's  
on a domain just because I know I would likely forget to update my  
own if I had one.  So I'd still be reading the same number of  
documents, just in a different order.

Peace,
Scott
