When people think of "an edge tool for academic writing", LaTeX may be the first software that comes to their mind. Indeed, the mathematical formulas written in and academic articles typeset by LaTeX are very beautiful. But an ordinary user who has used LaTeX a few times could hardly like it, because its syntax is a markup language that is essentially designed for the machine, not for human to read - just as the HTML source code is designed for the browser, not directly for Internet surfers.
