MediaWiki interprets ''' as <strong>. But most pages 
created with MediaWiki are for Wikimedia projects, which 
aren't like most other Web sites; most of our uses of bold 
are for defining instances <dfn>. Very, very few are for 
strong emphasis. Since Wikimedia project contributors are 
unlikely to care about the distinction between <dfn>/
<strong>/<b class="vector">, articles would sound more 
sensible if ''' was interpreted as the neutral <b>.

(Possibly new syntax for defining instances, strong 
emphasis and vector spaces could be created later for those 
thoughtful enough to use it. To increase the number of 
people using <dfn> correctly, the default style sheet could 
style <h1>-<h6> and <dfn> with the same non-black color.)
