This site offers 110 suggestions made by actual bloggers on how to improve a blog! While a number of them cannot be applied to my course blog (I'm not collaborating with anyone else, for example), there was still plenty of relevant advice. Even though I am given the topics to cover, I can still let my own personality come through. This relates to the course outcome of performance; a blog needs to feel like it was written by a human being and not by a robot. I could also start adding videos that contribute to my audience's understanding. I know that the sample rhetoric on the town assignment included a video of the advertisement the student had analyzed. Another good suggestion is to break up the paragraphs, which I try to do, or use bullet points. Another blogger suggests using subheads.

This Webpage is a bit long but it has some interesting ways of looking at rhetoric and problem solving. I recoment you skim throught because there is some interesting findings.
This website is a comprehensive look and provides information on the key concepts and strategies of rhetorical thinking. Check out my blog for the other two sites/links I found:a glossary of rhetorical and critical thinking terms and the Society of Technical Communications - an organization we may all be a part of someday.
