vCard - Old vs. New?

Dear all:

As far as I can see, there are now two vCard variants in use - the original

http://www.w3.org/2001/vcard-rdf/3.0#

and the new one

http://www.w3.org/2006/vcard/ns#

Now - which one should data providers and application developers use? I 
see the technical advantages of the new variant and the deficiencies of 
the old approach. However, a quick SWOOGLE statistics shows that there 
are only 470 RDF documents using the new version vs. 233,595 documents 
using the old version.

How do current Semantic Web applications handle this issue? Do they 
honor data expressed in either variant?
I see that Yahoo Searchmonkey, for instance, endorses the new namespace 
- what's with others?

We should not irritate potential users of Semantic technology by already 
confusing them by two vocabularies for such basic data as contact 
details....

Best
Martin
