I don't mean this sarcastically but what's wrong with quora? I've always found it to have pretty good content but your comment seems to be implying it's assumed to be a bad place to read things. Why?
Yes - A LOT of pushback. I didn't purchase it, and I don't complain about the ads because I understand they have to make money. I do read the comments on them and they are exclusively sarcastic comments/complaints about the ads existing.
My complaint isn't about the ads existing - it's more a disappointment in Reddit/Alexis Ohanian/YCom/etc in not being able to produce a more interesting business model. There is always so much talk about being "thought leaders" and focusing on really game changing technologies. This is the opposite of that : /
Also, if you don't use Alien Blue (the mobile app for Reddit) then you might not know they have been testing "Sponsored" posts. It didn't take a genius to know people would complain, but the ads are getting A LOT of pushback from users. I supposed you can put this in context and look at how Facebook gets crap for changing anything, but is this really the most creative idea Reddit can come up with to generate more revenue?
