Hi Rachel:
I make my living from building websites, and I respect your work immensely. What I really respect is that you have crafted an easy to use product and you are not afraid to put a value on it, as opposed to trying to monetize it obliquely. Reliability is the #1 consideration when choosing a CMS or any product. Our sites have to be built to last for a long time and be adaptable to future use. There are many people in our industry whose job is entirely to try every new tool that comes out, but the majority of people I know find a set of tools that they can use and feel comfortable with and for the most part, stay with those.
I use WordPress, because it is flexible, and familiar, and more extensible all the time. If I were to switch to another CMS, it would likely be either Perch or Concrete 5. The people who rely on Perch are pretty notable names, and I trust their judgement.
