Scandals like Cambridge Analytic are signals of change on the horizon, even if mere blips in the long-term. It would appear people are valuing their privacy less and less these days. There is enough evidence presented here to substantiate the claim on this diminishing values-based and social trend. Therein lies the challenge, how might we get people to rethink their privacy? To challenge their beliefs/assumptions about privacy in the digital era. Without a shift in consumer thoughts, values and behaviours can we really kill Twitter?
I would say Facebook and Twitter indeed have the first-mover advantage (though there was MySpace before Facebook). The reason they have so many users is because they keep evolving their features and add/copy from other services. I remember Facebook adding status updates (a copy from Twitter), # links for topics (another copy from Twitter), story feature (a copy of Snapchat) and others. 🙄
