Could you help with some open source PHP research?

A well known market research company is currently interviewing developers about the adoption of various PHP technologies, particularly in open source circles. If you are:

* Programming professionally with open source tools, for revenue-producing work (that is, not inside-the-company-only apps)

* In the U.S. or Canada

* Using Joomla, Drupal, SugarCRM, phpBB or WordPress

* Willing to answer some questions (both online and, ideally, by phone)

Your information is, of course, kept entirely confidential. Participants will be sent a summary of the results in early summer; those who do a phone interview will get a $25 gift certificate from Amazon.
