I'd like to take issue with this comment from the author:
Quite simply, anyone who is writing non-trivial documents and is tired of being let down by the performance of the current crop of word processors. If you are in academia, you really ought to be using it!
I'm sorry, but this is just not true outside of math. The majority of the academy is absolutely dominated by MS Word to the point it's almost impossible to work (for example to publish) without it. I manage to, but I use XML for document coding because I find it a much better solution than LaTeX for my needs.
And yes, I have years of experience with TeX.
