However, the age of the rally is waning these days. It was all the rage during the French Revolution, but telephony and television have created much better influence tools; such as the phone-in campaign or the political ad buy. It would be good to at least upgrade to '50s style politics and organize people for either phoning in to Congress ("OK Bob you want to help? You can call congressman Goodlatte's office around 3pm this Friday, here are some possible talking points") or running Kickstarter-style ad buys ("Donate $5 for running this ad on prime time national TV and we'll post your name on our wall").
Of course, the Internet offers new possibilities for politics that have barely begun to be scratched. Everyone uses Google, and Google is a democracy of sorts allowing for tactics such as Google bombing. It's hard to quantify its effect on the presidential campaign of senator Santorum (Republican runner-up last year), but it was probably out of proportion with the small number of people involved. And I'm sure there are many other things possible, if only more smart people directed their attention towards such issues. Politics is important - it won't make you as much money as a successful app, but can change the world a lot more.
