If Spock works…it could be an interesting way for individuals to clean up their identities on the web. Think about your students with “2sexxxy4u<at>yahoo.com” email address, or, other stuff graduate students have done and don’t want found when they go on the job market? Although I don’t see this tool being anything that I would specifically build into a lesson, I can imagine having some interesting discussions about it, especially in my technical writing class. Our tech writing course curriculum requires that I have the students write a job application packet. I think it could be interesting to discuss the hows and whys a site/tool like Spock becomes necessary. It might also be a great discussion to have with students before asking them to open/start some new account.
