There are some decent LaTeX to HTML converters out there too (have been for years).
I've been thinking about making a simple "free-ish text" converter that produces only LaTeX. It would be a LaTeX helper of sort. It would allow a casual user the ability to produce very high quality print without the learning curve of LaTeX.
The trick is, the "almost free text" format markup would have to be beautiful. The idea is "beautiful plain text in", "beautiful print out".
What if everyone could produce beautiful print? What would you typeset?
