Does blogging make a difference to your teaching?

I have often felt that as soon as a course finishes that it's time for the next one without having the time or energy to reflect on the course,my teaching and the experiences of the learners.I have a class Facebook page that I manage which forms some reflection even if it is just a visual record.I have recently discovered this great blog all about the experience of reflective blogging as a teacher and using a class blog which I will start to do next week.http://reflectiveteachingreflectivelearning.com
