I'm thinking of starting a project that is aimed at creating a simpler syntax for LaTeX, for cleaner and speedier document creation.
Check out the project notes, ideas, and examples at http://github.com/chetan51/eX.
There already exists a syntax called Multimarkdown, but it doesn't support a lot of basic stuff (AFAIK) like multi-line equations, theorems, etc. Basically, it's not as simple or specifically tailored for LaTeX as I would hope.
My vision is to make simple LaTeX document creation easier and faster using this shorthand notation, and to make LaTeX more accessible to the non-technical masses.
What do you think? Is this a project worth spending time and effort on? Would you use it?
Sounds like you're targeting much more of the latter group to increase accessibility. However, for that group of people a few LaTeX IDEs already exist that make it even easier than typesetting with a simpler mark up.
A lot of very smart people have spent a lot of time thinking about (La)TeX formatting, syntax and interaction and I doubt giving it a simplistic interface will do it much justice or introduce it to someone who found the original markup inaccessible.
Just my $0.02.
