May I chime in?
His comments made quite a splash two years ago when he was running for re-election (Note post date). Nothing much came of it (except that he was re-elected). As noted in the article, he also sponsored legislation banning access to social-networking Web sites in schools and libraries.

Teachers face battles over internet/site access every day. I think his reaction is part of a larger question/concern. As K-12 EDTEC thought leaders in our spheres of influence, what knowledge and principles can we bring to the table that will help establish policies allowing our students appropriate online access? If people are worried about content, is legislation banning technologies always the best reaction? What other options are there?

Also - We know enough about SL now to counter some of his concerns. 1. He wasn't in Teen SL 2. You can "lock down" an island on TSL solely for students.

... Just adding my post-breakfast two cents. Feel free to heartily disagree and dissent! :)
