Readers of the Digital Education blog may be interested in checking out this post on the Teaching Now blog about the latest developments of the social networking site Ning, which hosts many teacher networking communities. The free service announced last month that it was moving to a subscription-based model.
Update: My colleague Michelle Davis has a story about this up today on edweek.org. One of the folks she interviewed, ed-tech guru Steve Hargadon, also has a post up on his blog about the changes with Ning.
