Ask HN: Too much copyright VS abolishment of intellectual property?

I just found a company devoted to stopping, or at least finding, plagiarism on the web.

Here's their page about plagiarism: http://www.copyscape.com/plagiarism.php

And some testimonials from a rather wide variety of well-known "clients" : http://www.copyscape.com/press.php

Being both a producer and a consumer of web content, I've often found myself caught between freely distributing things that I produce and adhering my name and copyright to those things.

I understand the motivation to protect the ideas or intellectual products one produces for either credit or profit, but I also see the folly of trying to actually stop the dispersal of information or data which people want (DRM, for example).

Your thoughts?
