In reply to Jeff Chandler.

The survey was conducted by Survata, Inc. and targeted respondents older than 18 who reside in the United States. To be included in the survey, the respondents had to answer "Yes" to the following screening question: Have you managed a WP blog or website?

We did not request further screening questions around whether respondents were beginners, casual, bloggers, power users, or beyond (terms from BobWP).

The feedback everyone is leaving here is great as we can incorporate it and do better next time. This was our first formal survey.
