Well I actually meant dcterms:creator when I wrote dc:creator, sorry. So 
you can link your personal tags to your foaf profile, for example.
And it's consistent even for tag:AutoTag, since the range of 
dcterms:creator is dcterms:Agent, including person, organisation and 
software agent as well.
Unless I miss some sublte distinguo dcterms:Agent is equivalent to 
foaf:Agent, and dcterms:creator equivalent to foaf:maker. BTW, with due 
respect to danbri, I wish FOAF would be revised to align whenever 
possible on dcterms vocabulary, now that it has clean declarations of 
classes, domains and ranges ... 
http://dublincore.org/documents/dcmi-terms is worth (re)visiting :-)
