Preview/Trailor ideas

At this point I am still pretty unsure about what I want to do my trailor on. I love music and photography, but I want to do something that nobody in class is doing. I don't want to seem like a copycat. I interested in how relationships between people things like family, friends, etc. have changed since the advent of social networking groups like facebook, myspace, and twitter. I know that this is a popular concept for the assignment, so I am still not sure how to spin this idea. I do know that personally, my relationships have been affected by these groups. My 5 year class reunion is coming up in June, and the only way that we have to get in touch with one another is via facebook and myspace. I am also very interested in the idea of doing my trailor on how once you post something online it then becomes public domain even if it was intended to only be yours as well as to be something that is pleasureable, it can eventually come back as a bad reflection on you.
