In the past, I've added ID attributes to pages with multiple hCards  
thinking this would be useful for taking actions on specific  
contacts, but then discovered that most tools didn't recognize  
fragment URLs.  Last I checked, I believe X2V wasn't recognizing  
fragment URLs, so it wasn't possible to export a single vcard from a  
document containing multiple hCards.  To work around this, I made a  
proxy service to strip documents down to single fragments:

http://makedatamakesense.com/fraggle/

For example, Tantek has 26 hCards on his home page, but you can pull  
out just his own by running the page through this proxy:

http://makedatamakesense.com/fraggle/?url=http%3A%2F%2Ftantek.com%2F% 
23hcard

And then I went back and looked at X2V again, and now it seems to be  
recognizing fragment URLs.  Technorati's vcard export still ignored  
the fragment in URLs, so I thought this might still be useful there.   
But it seems to be doing some odd conversion of URLs that makes this  
impossible.  This:

http://feeds.technorati.com/contacts/http://makedatamakesense.com/ 
fraggle/?url=http%3A%2F%2Ftantek.com%2F%23hcard

Becomes this:

http://feeds.technorati.com/contacts/http://tantek.com/#hcard

And it converts all 26 hCards.  So it looks like I wasted a little  
time on that proxy.  But if there is some service out there that  
doesn't recognize fragment URLs, and anyone wants to take advantage  
of ID attributes on microformats, you can use it.

On a side note: as I was going through the hCard examples looking for  
pages with multiple hCards to see if any of them had ID attributes  
already, I noticed a lot of pages in that list don't actually have  
hCards at all.  For example, I remember Neil Dunn once had a nicely  
styled hCard on this page, but now it's gone:

http://www.ndunn.com/2005/10/7/hCard

So what's the protocol here?  Should such links be removed from the  
wiki?  Moved to a "formerly had hCards" section?

Peace,
Scott
