Writing terms and conditions is a nightmare, one for the lawyers, but it has to be a document written in plain language so the everyday user can understand what it really means. The terms and conditions have to be written by those who are intimately aware of how users engage with the system. And most of us don't read those documents properly, unfortunately, unless there is a problem.
One of the difficulties with social networking sites like these is that information provided by users is mostly interlinked with others' content. If I write a comment on your blog or your Facebook wall, who owns that comment - you or me? If I leave that community, can I take all my messages with me, not only on my wall, but should I also be allowed to rip them off your wall? Or do you have rights over that content as it resides in your space?
Copyright and IP law is a minefield. Facebook has reverted to the old rules until they work this one out.
