A welcome question, Clark. Quora Inc does not have an opinion. The Quora community does. Actually, it has several. The question Is there a considered etiquette on Quora as to whether you ask questions anonymously or not? is a free-for-all.
I like this as a list of what topics make sense to ask about anonymously:
If you’re asking a question anonymously about, I dunno, chord progressions in Liszt, you will get people annoyed about you being anonymous. (Some people do that because they don’t want to admit eponymously to ignorance. I don’t get that, but that’s me.)
If you’re asking a question anonymously about why you’re being mistreated by Quora moderation, so noone has any way of checking what the hell happened, you will get pitchforks.
If you’re asking about things that could compromise your safety or your privacy, you will get a sympathetic ear from the critical mass of Quorans who are not assholes.
