The stats show a large number of infrequently used tags, many of which
are not in the spec. They also show a large number of incorrectly used
tags that are in the spec. All these represent write-only data. One
response to this is to ignore it. Another response to this is to make
efforts to encourage validation against an agreed spec. I've suggested
this in the past but have been told that "Validating FOAF" does not mean
anything except in the sense of validating against RDF. And that
validating against the spec is back to front because the spec is a
reflection of current practice not an arbiter. So Libby's (sorry to take
this as an example, Libby) FOAF file is just as valid as mine despite
the fact that Libby's is so far from what I can code to expect that it's
essentially unusable to me.

Indeed. I don't want to experiment with RDF tools chewing on data. I
don't want to raise awareness of the expressive power of multiple
namespace documents. I don't want to enable semantic homepages. To be
crude and somewhat tactless, I don't want to live in an ivory tower.
I want to write apps.
I refuse to take this as evidence that I don't understand or as a
reflection on my coding skills ;-)
