2. What are some suggestions Wael Ghonim tells his audience for how we can “liberate the Internet”? He makes some suggestions but here are four suggestions he made. He said,"But what if we put more focus on quality?" "Couldn't we just give people more incentives to engage in conversations, rater than just broadcasting options all the time? Or reward people for reading and responding to view that they disagree with?" "What if we have a matrix that says how many people changed their minds, and that becomes part of our social media experience?"
