“The documentation and community are second to none.”
“[W]e’ve found that people …can get up-to-speed relatively quickly
thanks to the excellent documentation…”
“Django … provides an excellent developer experience, with great
documentation and tutorials…”
“Our initial choice … was based on the strength of the
Django community and documentation…”
“Productive development, good documentation, flexibility,
and it just works.”

Our technical goals are to never lose
data, be very fast, and favor boring
and faded technologies where possible.
A rule of thumb that has worked well
for me is that if I'm excited to play
around with something, it probably
doesn't belong in production.
