i) it is four taps on snapchat, no? just did it again and for me it's 4 vs 1 ii)that is true - i guess if you really want to nail a more personal / 1-1 service you need to have some constraints around broadcasting iii) same - if you want it to be personal and authentic you need constraints around that. but good questions, i think if you just try it - it is easiest to experience the differences
three things: i) it is much faster, 10x. it's one tap to send a video or message to someone by just holding their profile pic in a gird ii) it's purely 1-1 so every message is for you, no broadcasting iii) it's very authentic as there are no retakes, filters, etc
