The "We the People" petition site needs more mainstream petitions to be credible. The problem may be their 150 signature threshold. I submitted this comment to the website:
When a new petition is submitted, you search for similar petitions to help prevent duplicate efforts. But you only search petitions that reached the 150 signature threshold. As a result, you are getting a lot of similar petitions below the 150 threshold.
The 150 threshold favors fringe ideas with existing organized support. Many mainstream ideas do not have organizations behind them. So mainstream petitions are trapped below the 150 threshold, even though they are submitted many times by several different authors.
To make your petition website credible, we need to see more mainstream ideas. You can help by searching all petitions for duplicates when a new petition is submitted.
