I think I disagree, but it would depend on implementation details.
One possibility I can see is that you keep around a copy of the LaTeX distribution to parse these easily embedded LaTeX fragments, something like LuaTeX might someday turn out to be. In that case, you're still stuck supporting LaTeX's monstrosity of a toolchain. In that case, there's still e.g. no LaTeX on the iPad.
Another possibility is that you rewrite the LaTeX engine ... ah, nevermind, this isn't a possibility.
The recent document publishing efforts at SIAI would not have been possible without the assistance of dedicated volunteers. This new project is the perfect opportunity to help out lesswrong while giving you an excuse to catch up on (or revisit) your reading of some foundational rational thinking material. As an added bonus every post reviewed will save the world with 3.5*epsilon probability.
We need volunteers who are willing to read some sequence posts and have an eye for detail. Anyone interested in contributing should contact me at cameron.taylor [at] singinst [dot] org.
For those more interested in academic papers we also have regular publications (and re-publications) that need proofreading and editing before they are released.
