I recently came upon this great blog by Dr. Anne Marie Cunningham, a general practitioner and Clinical Lecturer at Wales, UK. She has some really insightful posts about education, its future, and the use of new technologies. This blog has been in existence since 2008. Just as interesting are the tons of comments that she gets from a spectrum of readers. Check it out!
She is also extremely active on Twitter with over 2,000 followers (@amcunningham).
