This is really useful, Sarah. I tend not to think much about this. While I blog in a public space to engage in reflective practice, I often do not think much about my audience. I know, not the best thing to do (especially as a management communications faculty member), and perhaps that is a piece of this–I write primarily for myself, rather than for an audience that may be interested in this or that. The fact that some people, such as you, are kind and interested enough to take a peek here every now and then is a wonderful incentive to keep writing.
Perhaps my audience is both myself and my peers?
