Pandoc is Super Awesome
In the past, I've used a couple of nice LaTeX templates for various types of documents. I had a homework and project template, a letter template and a couple random ones. I've also used Beamer for snazzy presentations. The results, as always where LaTeX is involved, are lovely. However, editing a full-on Tex file for each document usually seemed like overkill. In most cases, I just wanted nicely formatted text, usually with a couple equations or code snippets.
Then I discovered Pandoc. Pandoc is an incredibly powerful "document converter". It can convert between a variety of text-based formats (HTML, LaTeX, Markdown, ODT, and many more). But the nicest thing about it is that it has its own superset of Markdown that supports all the features missing from vanilla Markdown that make it inappropriate for complex documents (tables being one).
Pandoc can convert its own (or vanilla) Markdown to many other formats, among them PDF (through LaTeX). This is a tremendous advantage for creating attractive documents without too much effort. I can write up an assignment or project using Markdown and get a lovely PDF directly or, if I really want to fiddle with the LaTeX I can just convert the first draft to that, and go from there.
Pandoc also supports templates and has its own template system, which makes customizing the result for different types of documents pretty simple. You can even put LaTeX code inside a Markdown document and let Pandoc sort the whole mess out!
