I'm a long-time user of free/open source software, and write various things for both fun and profit. I don't take myself all that seriously and I do all of my own stunts.
You can find me at these fine establishments on the web: Open Source Musings, The Monday Kickoff, Weekly Musings. and The Plain Text Project.

NeoVim is pretty neat, but that doesn't mean it (or Vim) is for everyone.
I've found that it's easier to work with graphics in DocBook than it is in TeX or LaTeX. As with anything, it's all about what you need to do. In those rare instances I need to create a shorter document with a more complex layout, I turn to Scribus. But when I need to output a longer, nicely-typeset document I'll turn to LaTeX or DocBook.
