I browse Quora quite a lot, but I only follow writers I like, and no topics, to avoid exactly this. The average answer quality is dreadful.

I think the point about shamelessly pretending to understand, though, is a subtler question, and difficult to address. I follow people on a lot of topics I don't know about, and I've occasionally discovered later down the line than they're full of crap. And I realise in retrospect that I've helped them do it, upvoting seemingly well-researched answers because I appreciated the effort.

It really highlights the difficulty of figuring out who to trust when there's no central authority, and I could see myself being drawn into some reality-denying group a la flat-earthers or antivaxxers just because I happened to follow the wrong people at the start, and on their advice reject other answers.
