Following on from this question I propose that formatting which can be used to make an answer look grossly different to the general look of answers on SF. e.g.
This kind of thing should not be allowed in answers.
I must stress that I'm talking only about answers in this instance. I've seen some cases, such as our recent FAQ discussion, where it is useful for questions, provided of course that it's used with a little discretion.
I do realise this would require a change in the parser which reads the post which may be common to all of SE but that can be solved quite easily using one or more flags for those sites which wish to limit the formatting options.
It's pretty clear to me that this is a distinctly less than popular idea. I would point out however that those posts being put up as examples of why others don't want this change are the very same ones I would put as examples of why I do want it. With that said I'll drop the subject.
