Tweet, tweet!

Twitter seems like it could be a very useful tool, especially if you want to have instant contact with someone overseas. I thought the short discussion of confidentiality was interesting. I'm still "old-fashioned" and really don't want everyone to be able to see what I'm writing, so the lock down feature was a good addition. To me, it's strange and a bit frightening that some teenagers are so willing to share pictures of themselves or personal information. Definitely would need to discuss safety concerns with students at school.
