I'll pass this question to ..
Can you imagine her answer with not less than 25 smileys + LOLss.
I guess, after seeing her LOL and " 😀 🙂 " answers, Quora admins decided not to include emoticons/smileys.
Quora is pretty serious about the content we post. The moderators moderate each and every questions and answer we post. Bringing smileys or emoticons in answers can bring down those seriousness because there are still users who just put a single smiley for a very good question, which in turn can lower some users interest in that particular question.
