I have spent a few hours every day on Facebook for the last month compiling an event where people can go to debate current issues and have (hopefully) all of their questions answered. Over 85,000 people have joined in the last 3 weeks. Every day I have hundreds, sometimes thousands, of new wall posts to read in the event. I have read every single wall post and if somebody asks a question I do my best to answer it. The information I put on the page is unbiased, despite the fact that I usually have very strong political opinions. When I put up new information or answer a question, I usually remain very formal in order to avoid any references to my political decisions.
Common questions that I have answered have been: Where can I vote? Where can I register? Where can I learn about the candidates and what their stances on the issues are?
I have a section on the page where people can volunteer to represent their state, congressional district or country (if they're voting absentee), and many people have e-mailed me to tell me that they have become a lot more involved in their areas since they became reps on my page. One of my state reps for Texas created a debate group on Facebook for people to have real debates in, and it has gotten off the ground nicely in the last couple weeks.
Even if I hadn't impacted anybody else, everything I've been reading over the last few weeks as research for this group has made me consider changing my vote for the November election. Since I truly believe that every single vote matters, I feel that this event has been worth it.
