I think this will be worse. Snapchat isn't nearly as culturally sticky as Twitter. Sites like Twitter, Instagram, and Facebook have a robust friend/follower system, and users have a huge backlog of things they contributed to the platforms. No contributions on Snapchat last more than a single day, so what is motivating users to stay on the platform instead of using Facebook or Instagram's offerings? Their friends lists exist both of those places too. In 10 years we'll look back on Snapchat as a flash in the pan.
