Hello!
I didn’t mention it but here are rough guidelines that I think we should
follow for blog posts:
• It should indeed be about free software and not promote non-free
software (it’s also a good idea to follow
<https://www.gnu.org/philosophy/words-to-avoid.html> IMO.) So the
topic of patching non-free binaries wouldn’t fit the bill, for
instance.
• It should be understandable by someone who’s not a die-hard Guix
or Scheme hacker. :-) So it’s good to provide enough context,
possibly with links to relevant parts of the manual, previous blog
posts, etc.
• It’s good to use appropriate Markdown markup (ah ha!), like
backquotes for file names, command names, and so on, or “```scheme”
to introduce Scheme snippets. See <http://spec.commonmark.org/0.27/>.
Apart from that, anything that teaches people how to solve a problem or
that explains neat hacks in or with Guix(SD) is very welcome IMO!
Articles don’t have to be super long or take days to write; more
informal or short articles can be useful too.
