This might be a coincidence but either I remember seeing that question on Quora, or it simply gets asked a lot.
I also remember the answer about how things didn't work like that and I thought to myself "hmm, I agree, but he's not really answering the question though" - It might also be because the answer came off very negative and degrading
So I actually flagged the answer as "not helpful".
I'm guessing more people did, so it wasn't any single person.
Personally, I'm pretty happy with how these Q&A sites work. I don't feel that it's just to serve the search engine results. I think they genuinely help people.
