I find that personas are nearly useless for this kind of design discussion. Personas are an attempt to homogenize some group of people into a single pseudo-person that has specific attributes. When the lines between personas are hard to draw or there are so many lines that you wind up with lots of personas, you can find yourself spending lots of time managing personas without a ton of direction or solving anyone's problems.

For a heterogenous audience like "web makers" of various types, an activity centered approach can be really helpful. Don Norman explains this idea better than I ever could:
