George Siemens, on his Connectivism Blog http://connectivism.ca/blog/2007/10/digital_natives_and_immigrants.html wrote about this last October. He makes some interesting points and those who commented have more to add.
Also, David Thornburg apologized in a blog post for using the term: http://thornburgcenter.blogspot.com/2007/10/tl-conference-and-apology.html
Jamie McKenzie writes his indictment of the term last November: http://fno.org/nov07/nativism.html
All of this to say that we have to be careful with our labels and generalizations. We must be discerning with these kinds of divisive ideas or we’ll end up with a digital Lord of the Flies with our kids on the island without us.
