Love the ease of YouTube for finding video, but you really need to preview everything. I like having kids see what other kids are saying, but they often forget about some language issues when posting.
I hope to use Dropbox to video my seniors about their experiences looking for colleges, majors or job training that aligns with their interests and skills.
As usual, copyright laws are a mess and very hard to decipher. I like the fact that many new sites being used, such as TurnItIn.com have filters that scan for it. That makes it easier for the kids to see their mistakes and fix them. My own kids have found this very helpful, especially when mom isn't around to check and edit!
