Cheryl has been research-blogging for some time now (since the fall of 2008 to be exact). Her most current active blog is called Electric Ladies Zap, which has been up and running since December 2011. You can access Electric Ladies Zap here.
Cheryl started her first research blog in 2008 at Georgetown University while she was getting her Master's and working at Georgetown's Center for New Designs in Learning and Scholarship. She began her blog at the very beginning of her Master's program, which means that much of her intellectual trajectory is archived there. You can access her Master's blog here.
