I know the significance of LaTex as I use it regularly for my work. I am not sure what something Resumonk uses - doesn't look like LaTex. Great, so LaTex seems to be the niché.
Have you seen templates hosted at "LaTex Templates"? [0] I would be curious to know if you're using them or plan to use them in the future.
Yes they usually use HTML and then convert it to PDF. This leads to a lot of problems in alignment etc & the print quality is also not great. And for the LaTeX templates. We are currently using existing templates. We plan to allow create custom templates soon :)
