After I published last night's post on reasons to have a classroom blog, a handful of people contacted me for recommendations on which blogging platform to use. The answer isn't always clear cut as every teacher has his or her unique classroom dynamics to account for in making a choice. That's why earlier this year I created the chart that you can see here on Google Docs or as embedded below. The chart evaluates key aspects of seven popular blogging tools. At the bottom of the chart I provide a summary and ranking of the tools.
