Do people really copy snippets they found on a website into their code? I use examples on the web to further my understanding of a technical issue but would never cut and paste blocks of code. Aside from the copyright uncertainty, I simply wouldn't trust a piece of random code found on the web enough to pull it into my own. That said, I do agree that if you've make choices in your code based on information that you found online, its good to include a reference to the source in a comment.
