Just wanted to toss in a +1 for MMD within vimwiki. I think that
interoperability with the various more traditionally "pretty"
applications is kind of important for the future of vimwiki (read: I
am still looking for a reasonable way of interacting with vimwiki on
my mobile, which maybe deserves its own thread) and MMD seems like a
pretty good path for that, in that it seems to strike a good balance
between platform agnosticism and attractiveness to non vimheads.
