You mean why write LaTeX? I write latex because most of my work eventually ends up as PDFs in journals, and there nothing comes close to comparing to LaTeX's quality. When I use markdown I end up using LaTeX extensions to write the maths anyway. However, it would be nice I could get better html output, as PDFs aren't nice to view online.
