Hold a public announcement where you address the top 10 petitions according to signatures and not convenience.

I look through the petitions and I look at the responses but it seems like the white house only answers convenient questions. They should answer to the top 10-20 petitions on the site. As well as promote this site through commercials and other means to let people they can vote on issues that will actually be answered. This is a great way to get America involved!
