I do not see steps 4-7. After 3, I stay on that page. Sometimes in the past I would see an overlay on that page. I don't get redirected anywhere, and I'm 100% sure I never was (there was only popup). I wonder where's the discrepancy coming from.
Also, google bot would be redirected too, unless of course it's simply logged in :)
I could make lots of guesses why you don't experience Quora the same way I do. None of that would change the fact that I can't see the information I am being promised to see on Google.
Here is a screenshot of the page I am being forwarded to automatically: http://pho.to/Aatuj
It is a disguised register page because after you make 10 selections, you are forced to sign up.
That's because you got fooled into making an account. It's trying to get you to complete the registration process so they can pick questions to show you.
If you clear your cookies and go from a Google search result to Quora, you can read the answers on the page that you're on. If you navigate to any other question, say via the links at the bottom of the page for similar / related questions, the answers will be blocked by the signup popup.
If, instead of signing, you go back to Google and search for the same "<question> quora" it'll work again. The thing to remember is only the first page you navigate to from Google will display properly.
That's because you seem to be halfway through making an account and they want you to finish.
The actual behavior of Quora, if you aren't midway through account signup is:
if you go through Google search it shows you the page promised.
If, from that page, you click on another question it will open the second question but give you the sign up modal. You can bypass a signup modal and get the normal page by appending ?share=1 to the end of the URL.
I don't even have a Quora account but I read the ?share=1 trick a while ago on hacker news.
I saw your video. It looks like you are in the middle of a, probably accidental, new account signup. Maybe you let your kid use your phone weeks ago and she did it. If you clear your cookies then you should get the behavior above.
I don't "expect" users to do anything, I was sharing a known workaround in case anyone was interested.
EDIT: I just created an account to see what happens. You are logged into a new account. Maybe you accidentally logged in with Google?
I created a new account with a fake name and email. No email verification. After the fake name and email is entered they ask you to follow topics (which is the screenshot you are seeing) and once you pick 10 your account is "complete" and they will let you look at the answer.
When I made that quora complain before, HN readers are kind enough to show me how to avoid it. Without the ?share=1 trick, I probably don't even know how Quora looks like.
Also, google bot would be redirected too, unless of course it's simply logged in :)
