For some definition of "worked" ... sure, you signed up. Then what?
I already had an account when Quora did it, and that made me use it less (wasn't always signed in, wasn't always willing to sign in - e.g. incognito sessions). For a long while, I started going back less and less - was only brought back occasionally by their emails which were still pretty good.
Recently the emails got so bad that I unsubscribed (I kinda expect to stop visiting the site completely). So I'm guessing I'm not alone in reducing my engagement - the quality of the whole site seems to have gone dramatically down.
The thing that slowed my usage of Quora down to basically once every few months is so many of the answers to sincere subjects are promotional for some product someone's pushing—even if it's actually off-topic but some damned keyword aligned!
I liked it before that kind of activity proliferated the space.
Quora is particularly annoying in this regard. I too refuse to sign in oftentimes when they force me to.
When a service puts its core usefulness behind an unnecessary login then they are forcing me to sign in, they are not making me want to. There is a key difference.
