Reflective Journal for My Doctoral Studies – Do It Online?

We just began our Module 2 in my Lancaster University PhD Programme in E-Research & Technology Enhanced Learning, and one of our assignments is to keep a daily reflective journal, perhaps one that is a 5-10 minute entry around the issue “What really matters in my professional practice?”

As an advocate of reflective practice and writing as a practice of processing experiences and making meaning, I like this assignment (and have even used it myself with my own students numerous times over the years), though am considering doing this here on my blog as opposed to in a notebook or someplace privately on my computer.

Has anybody ever tried this or seen this done, perhaps to offer some pointers, suggestions, warnings, or the like?
