I've seen a lot of answers within the last day or two that consist largely - or almost entirely - of quotes from authors or their works. I understand that it's always important to look back at the original source to analyze it, and that it's often good to then include those analyzed passages in your answer. I've quoted the original works in almost all of my posts.
However, I think there's a limit. I've seen several answers that contain just a quote and one introductory sentence giving a link to the source of the quote. I see that and I think, "The answerer couldn't be bothered to write something in their own words." See, no explanation, no matter how well-written, is ever perfect, and you can always improve on writing you find somewhere else. One of the goals of Stack Exchange is to be the best collection of questions and answers on the Internet. Doesn't that involve writing our own posts?
I'm guessing some people agree with me, and some people disagree with me, so I'd like to get a discussion going. Just how big of a role should quotes have in answers? Should they take up the majority of the text, in some cases, or is it better to have mostly original writing?
Some examples of questions that have gotten largely quote-based answers:
