I've noticed that as well, not about arranged marriages specifically but a ton of of ultra naive questions about relationships like, "Why do guys change their mind about a girl that they liked?", and "How do I know a girl is right for me?" (sic).

Those were literally the first two from my feed just then.

I used to find Quora interesting but it just has so much of this low-quality spam on it now.

For my feed it's all that or military stuff, which I do find interesting on occasion, so I do see why that's there.

I wonder if it's just our feeds or if the whole of Quora is like that.
