True, and I agree that there are some here.

Aside from this thread, perhaps you can set up a survey on your website. Find out what all users think on a range of questions from the product to e-on, and most importantly ask if they are using it for professional level work to more hobbyist activities. Also ask people for their email address and if they would like to be included in further surveys. From there you can build a database of the "type" of users that you can use for future more specific surveys. For example, the question of this thread would have only been targetted to those who consider their usage pro level.

Just a suggestion on how to better target your users and get better feedback than a general question to everybody. :)
