Interesting.<p>I read your article, expecting something totally different... which does not make your article less interesting.<p>I think that most of the time big ideas start small... in their respective non existing markets. Tesla was a big endeavor, but seen as niche (high end EV?), Facebook started as niche, etc....Even the Brazilian demonstrations or the Arab spring started "small".<p>The problem of many entrepreneurs I see is that think so big that they cannot think small and so they cannot start. Their product is fluffy and fails miserably.<p>So today, at 40 years old, your friends don't understand Snapchat. And yet, at some point, Snapchat may cross the chasm and Jay-Z will spend money to advertise his shows there, and in an era where privacy is going to become important again, Snapchat might - who knows - actually become the poster child of the evanescent private Internet.
