Input from the online public plays a large role in what sessions occur at the SXSW Interactive Festival. So get ready to vote for your favorite PanelPicker proposals beginning Monday, August 19. Voting is easy -- simply log into your PanelPicker account (or create a new account if you don't have one already). Then browse the nearly 3000 proposals and choose the ones that you think are the best fit for the event. Also, be sure to comment on why you voted for the sessions that you voted for. SXSW PanelPicker voting remains open until the end of the day on Friday, September 6.
