The author is clearly mistaken, but there's a point to the claim that la/tex is complicated, perhaps overly so for 99% of documents produced.

Personally I'd like to see something in-between latex and markdown. Just slightly more powerful than markdown. The first things I'd like to see added to markdown are labels and references.

At that point I think it'd be good enough for anything where fine tuned control over the presentation is not important.

Anyone using such extended markdowns that you would recommend?
