Edublogs announced today that there will no longer be advertisements placed on Edublogs-hosted blogs. This includes the free blogs that they offer. According to the announcement from Edublogs part of the reason for doing this is to try to reach one million blogs hosted by Edublogs.
Applications for Education
In the past, one of the drawbacks to using the free version of Edublogs is that you didn't have any control over the advertising that appeared in your blog. The removal of advertising from free blogs should enable more teachers and students to use a WordPress-powered platform in their classrooms.
Full Disclosure: Edublogs has been a paying advertiser on Free Technology for Teachers for the last year.
