That also assumes that survey responders understood the question the way
we are interpreting it. The actual question should have been:

What toolkits do you use to interface with the OpenStack API?
 * OpenStack command line (i.e. nova cli)
 * openstack python libraries
 * jclouds
 * deltacloud
 ...
 * other - please specify
 * none - wrote our own

If you wrote your own toolkit for accessing the OpenStack API what wire
format are you using?
 * JSON
 * XML

If you wrote your own toolkit for accessing the OpenStack API what
programming language did you write it in?
 * C/C++
 * C#
 * Java
 * Python
 * Perl
 * PHP
 * Ruby
 * Other (please specify)


Because the question as worded assumes far too much shared context and
understanding in what we were looking for. We all understood what we
wanted, but didn't unroll that in a specific enough way in the user survey.
