A 21st Century Dilemma

Interesting question from Ann Darling popped up in the comments of the Blocking discussion over at ISTE:

Is it ethical to use web 2.0 tools in classrooms knowing that our students must provide personal information to create their accounts?

Hmm. Talk about ethical dilemmas!

We all know that an alias and an alt Gmail account pwn any Web 2.0 log-in without giving away any personal information. We also know how annoying it is to have to deal with anons on blogs or discussion boards.

So, the dilemma: Do you let kids alt their way around outmoded firewalls and proceed anonymously through Web 2.0, or do you teach them to approach social media in an open manner and risk whatever consequences?
