My first reaction is that categories !== tags. At least in conventional usage, categories seem to imply an interface-based correlation whereas tags are applied to semantically identify an object.
For example, I might use the category "Smells like fish" on my blog for peculiar news stories yet I'll tag the posts with "news", "government" and "george bush". (Aren't you glad I didn't use an hCard example?) In that case, if you were to try to suggest that the category usage is parallel with the tag use, I might take umbrage. Quite obviously, "Smells like fish" isn't a semantic way to describe the content. OTOH, dealing with contacts might be different. It seems to answer this somewhat more scientifically, you might conduct a brief survey and find out if blogging practices carry over to contact management (my guess is that it will vary -- i.e. mailing lists are another kind of categorization). So ultimately, I think you ought be careful about the overlap between tags and categories, because they're not the same thing and I would doubt are meant to be used interchangeably. My somewhat-uninformed two cents.
