"The idea is very simple," de Alfaro said. "If your contribution lasts, you gain reputation. If your contribution is reverted [to the previous version], your reputation falls."
I don't know if this software will stick, but I think the idea has implications for educational blogging. For instance in the future more news will be user generated, so the question will be whether our information is trustworthy. One litmus test will be our information reputation. If one blogger has a history of only making social posts on MySpace and another has a history of posts filled with associative links to reliable sources, who will you trust?
If you haven't already, it's time to start thinking about the information trail you're leaving behind.
