No, it'd just highlight things people have ticked. And how many have done so. That's all basically.
That's like saying because 100,000,000 people buy marmite every week, then marmite must be a good thing to be eating.
It's a personal preference. Just 'cause you like marmite doesn't mean I do. Personal preferences are pretty meaningless to other people, on the whole. You should concern yourself more with what you find interesting, more than what other people are interested in.
As is, it's not incredibly difficult to find things that interest you - it's organised into tidy sections. Soon there will be a search - this will allow you check for existing topics before you start a new thread, and avoiding multiple threads existing for the same topic of discussion.
It's Cynical, btw. And I'm not being "cyncial" - just making seasoned observations from the data presented. And that quora looks as shady as the ex FB punks that founded it.
