I've used Quora it's very helpful and easy to sift through so many questions with so little effort, but it is NOT blockchain based.( https://www.quora.com/Could-we-make-a-blockchain-based-Quora?share=6501e06b&srid=upRLC )
I wanna download and try whatapp, can anyone post a link to download it? I couldn't find it in the playstore.
Also hats off to steemit for paving way for such awesome community. #steemians #whatapp
