Most public attention and opinions follow news' recap of rulings. Pose the effects of the ruling before it is concrete via social media.
Once news communicates the effects of a ruling, the true public opinion surfaces and which is later than needed. I love the idea of having the ability to be pro-active in the rulemaking process. Could public opinion or voting be generated by having a simulated ruling? What if... a news story surfaces on news.google.com the "FCC decides to obsolete the TV tuner by allowing Comcast to require set top boxes for all" where the ruling has not occurred yet, but a news story format communicates affected pros and cons. Public would likely cast their opinions and FCC could compile the data for a more encompassing view of pros and cons. Industry could pose their opinions too (must be ethical representation of themselves though). It would be nice to help create the news vs. being the effect of it.
