I can run a data-harness script on a debian machine with a local mirror,
if needed, and then I can put online the harnessed data.  I can even
schedule this on a cron-job, so that you can get fresh data every
morning.

Is such a harness script doable?

Sure.  And the tagging precision could give an index on how good is a
tag, and an indication of where the ontology needs reworking.  That
would be so cool!

It would be really subjective to assign such a value to tags, and
probably would require more effort than it's worth.

I'd apply the YouAintGonnaNeedItYet pattern
(http://www.c2.com/cgi/wiki?YouArentGonnaNeedIt) and leave this for when
we really absolute need it.  There are more important things we need
anyway now ;)

/me leaves to meet Free Ekanayaka and Kalfa to talk about debtags with
some glasses of wine in a local osteria.


Ciao,

Enrico
