If it's Stack Overflow, nothing stops you from commenting on it to update something, or correct it. I've seen many authors of both questions and answers edit their own content for correctness. Community Participation does indeed fix this.
I agree, a lot of people poo-poo Stack Overflow and deride copy-paste coding, but forget that 85% of the answer was correct. Minor syntax errors, or missing flags, are something you should find out on your own when testing the code. I've not found many copy-paste snippets of code that were good to go as is, but I've found the direction to the answer an at least, and often a good amount of help to implement the answer.
What I really appreciate are the answers that have questions with the reference material quoted, and then explained. Some contributors really need to be thanked for that, so I'm not surprised you could make a book of notes from the good content.
Technically, lunchtime is at any moment. It's just a wave function.
