But a conversation about online free expression would be nothing without contributions from you. From election protests to government whistleblowing to grassroots advocacy, we’ve seen YouTube users upload, watch and share stories that would’ve never received global attention before the Internet era. That's why we're inviting you to submit your own video that answers this question:
"What's the biggest barrier to free expression on the Internet, and what would you do to overcome it?"
You can go to our Moderator series here to submit ideas and videos and/or to vote on your favorite contributions from others around the world. Please participate by September 7, and we’ll showcase many of your responses at the conference in Budapest later in the month. We’ll also offer highlights from the dialogue on CitizenTube.
