Blogging should be seen as part of the note-taking and brainstorming process and not as conventional newswriting, says Amy Gahran on Poynter.
Blog your initial brainstorm, and use that to ask readers for their own ideas that can build on that; blog your research and your thoughts about the source; and blog your interactions and the conversations you have outside the blog.
She describes her blog as "a backup brain", or a public notebook.
"Get more mileage out of work you would have done anyway by changing your habits toward managing information and communication publicly. Instead of keeping your thoughts, notes, and conversations to yourself, post them.
"The advantage is that this information will probably become more findable and useful to yourself as well as to others. (Ever tried to find that old notebook where you stored interview notes from three years ago? See what I mean?) And, as I mentioned, it often can speed and enhance your learning process as well as increase your visibility and influence." (Poynter)
