I think it is important to for peoples idea's to be acredited. I find all to often that people "steal" work from others for personal gain. This happens often in school. I believe the information should be out there otherwise it would be pointless to garher information through experiments or studies but a copyright law is necessary. Many people pride their work, and often enough it is their lifes work, and if their is no way of insuring that it is protected by some kind of law their efforts would have been in vein.
