Andrew & Jon,

Under the old guidleines (V1) there was just a level 3 guideline about
distinguising between links -

10.5   Until user agents render adjacent links distinctly, include no-link,
printable characters between adjacent links.

Otherwise there was nothing about a "minimum clickable area". I think that,
as Andrew suggests, it is a usability issue that affects all sighted users
that are able to use a mouse. This is one of those issues where a blind
user, or anyone who uses the keyboard for navigation, actually has an
advantage. <G>

I don't believe that this is covered by WCAG 2.0 - I can't speak for the
working group but as a member of it I think that the question is how far
this issue is along the slippery slope between being an issue that
differentially affects people with disabilities and being a usability issue
that impacts users irrespective of disability.

I'm not sure of the answer to that, but it is surely not only affecting
people with disabilities, so that may have been the basis for it not being
