Yes it matters a lot. If you want to build an online community or social change website you are going to end up being recommended to use Drupal. Drupal's community knowledge extends beyond just CMS development but is now a expert community in online community building and social change websites. This is important to know because this growing user base has certain expectations and goals. This was clear from the interviews, maybe 4+/10 people fell into this category. We need to get a sense of how many Drupal sites are falling into this domain.
So...then add that as another category. You may be an accidental technologist building things for a death metal band. I suspect a lot of the folks you interact with fall into the social change category...and I agree it is important to capture.
Most of the folks were random people plucked out of #drupal-support or acquaintances of people in #drupal. I explicitly tried to not sample the CivicSpace folks and these results still came through.
However, another huge category is "HTML Website developer adopting a CMS platform" or "Process consultant learning to us collaborative tools" (the former is more technical in terms of web stuff, the latter is less technical).
Ok. Let me think about how to introduce that into the self description responses. I don't want to force stuff into the survey, that didn't come out in the interviews. But then this is more art than science and I do want public review to make sure the results make sense. Thanks for the feedback. Kieran
