I was just thinking about my "django" search results, and I thought about why the Django framework ranked so highly. The type of people that write about Django and link to sites covering Django, they could be the same sort of people who know SEO better than the site operator for a tribute page to a jazz musician. So that might not have been the best example.
That's exactly right. However, I should take into account the popularity of the different ones and put the most popular on top. This happens in a lot of cases, but not in this one, though doing so is on the list.
