Quora and Yelp are ao user-hostile I try to not even open their links. The mobile homepage is literally oath signin buttons...that is it. The blog article on mobile has the large follow button fixed to the bottom of screen, hoping I fat finger it to bail me out of my fav app (a browser) and put it on my device.
On a computer, at least browsing some questions is possible, but it is annoying they won't let non-technical users just see these questions on the mobile web.
I am sure spam & ad revenue is better for them, but there was a time where developers focused on making an app/site useful to attract signups. To be fair, Quora has never done this, but others have followed shit in te last 2-3 years.
I hope this is useful to some, maybe I'll even play with the data, but I can't support Quora by visiting the actual site.
