Actually I was thinking of the n-triples subset. Anyway the thing is I
have a web application that accepts input from various xml formats, one
of them is RDF/XML the application exposes various functionalities one
of which is returning an output format most likely to be useful for said
resource, so that a vcard in xml format returns text/x-vcard format, now
I have these RDF/XML inputs, I can just copy them out as RDF/XML add in
headers for Content-Location etc. or I could output n-triples subset of
N3. 

A lot of programmers seem to like the triples and find them more
comprehensible, are there any resources that indicate how widespread
tools are that consume the triples format, and how popular that format
is in comparison to the RDF/XML format?

Sorry to bother you on this.

As editor of the RDF/XML spec (revising the 1999 era syntax) what do you
expect me to say?  Use the one based on XML for all the advantages of
that.  I'm using XSLT, RelaxNG, expat, libxml and other standard XML
languages and tools to produce, consume and check it, as are many
others.

N3 is an RDF-based research language (that is, it has extensions that
are not RDF). It is an evolving work and has a bunch of issues, the
important ones I see are internationalisation support, content encoding
(it has one, UTF-8) and using a vast amount of [] ; , {} => := = etc.
syntax.

There is, however, a handy subset that might be picked out and I'm
looking at that based on the other doc I co-edit, N-Triples
http://www.w3.org/TR/rdf-testcases/#ntriples

but this is *xml*-dev not ascii-dev or www-rdf-interest :)
