Converting documents with pandoc

I would welcome comments (favourable or otherwise) from anyone on the list who has used Pandoc to convert documents between various file formats. In particular, I'm interested in the possibility of using it to write papers in Markdown format (using Pandoc's extensions), then converting them to any of ePub, HTML, PDF (via LaTeX), MS-Word docx/OOXML, ODF, etc. Pandoc also supports automatic citations and bibliography generation, a highly desirable feature. I plan to experiment, but, as always, comments from those who have taken this path already would be informative.
