As I have written here, part of the reason I blog is to organize and polish my ideas. I use two rewriting practices to accomplish this:
1. Present Dialogue Re-writes
If commentors misunderstand my writing or point out obvious mistakes or weaknesses in my thought, I will (right then and there) fix up the post. And I usually acknowledge doing so (if the change is substantial) in the comment thread.
2. New Linkage Re-writes
Months or even years later, when I am visiting another blog and for brevity sake want to linking to one of my posts (again, one of the reasons I blog), before doing so I often go back to the post I intend to link and re-read it to be sure it still says what I believe and is written well. If not, I fix up the grammar/spelling mistakes that I notice, improve weak ideas and logic, and maybe even touch up formatting or style.
Question to readers: I’ve heard other bloggers object to changing their posts. They view their posts more as journals, it seems — like diaries that show their thinking over time. What do you feel about my method? Do you polish up your blog?
