<p>Tags are created by people who ask questions.  To date--after three and a half years and some 35,000 questions--nobody has seen fit to apply such a tag.  None of the active high-rep community members have seen any need to create and apply such tags retroactively.  Although I would not necessarily object to their creation, I see little need for them within the network of tags that has arisen within this site.  I do have some concern that tags with "soft" in them could be viewed prejudicially, as if such questions somehow had less merit or interest than "hard" tags related to techniques and theory.</p>
