Well, it's kind of a catch-22.
If I can provide better and original content, I wouldn't fear pasting a quoted answer because I can answer that question directly and claim it as my own.
Then there's the issue that if I know enough to have original content, I probably won't share it on a forum to discuss because I would think...hmm... this is too vague of a details or this is wrong, etc. etc. and instead I'd probably be sharing a blog post I made where the details can better be lay-ed out and it can come off more authoritatively.
Btw thanks, it's nice to have two opinions affirming the TOS (I got the other one via pm) of Quora.
