From what I understand Snapchat has more daily active users than Twitter and also a user base growing much faster.
Given they are a $100B dollar company, they are far from 'dying'.
Meh, valuation isn't everything. Uber and WeWork also have high valuations, little tangible assets, but are bleeding money and have no clear path to profitability.
Whereas the HN crowd 'thought' they either shut down or got acquired. As always, they 'thought' wrong. Again.
It's hard to grasp the reality check here but they are far from 'dying'.
