Right to be forgotten?

As I was scrolling through Google Reader today, I found a story posted on MIT's Technology Review site.

Apparently there is a line in the film The Social Network, "The Internet is written in ink" (as opposed to pencil). This captures the idea that many middle school students learn the hard way-- what is posted online cannot be taken down. (I am reminded of the PSA in which a girl posts her picture on the school bulletin board and she takes it down but another replaces it, and every time someone takes the photo down,a new one replaces it.)

According to David Zak, http://www.technologyreview.com/blog/guest/26700/?p1=A5, the Europe, there has been floated a proposal called the "right to be forgotten." If passed, the law would require users to opt in to data collection by the web sites they frequent and they would have the right to ask information be taken down, and they would be allowed to sue to force compliance.
