The concept is that the Prime Minister reads the big and popular petitions, reads what wants to be happened and possibly do something about it. He then responds to the popular ones saying his opinion on the subject and whether he'll try and follow up with the issue of the petition.
Now, the problems I see are thusly: 1) He doesn't give two ###### what other people think - I've received two emails in response to two popular petitions. One of which was to scrap the incoming road tax policy - it received 1.8m signatures or something along those lines. What did he reply? Basically something along the lines of "###### off". There are ~60.5 million people in Britain. 1.8m is not a huge proportion of this. Would it have been right for the PM to change the Road Tax law based on 1/30th of the population? Around half of the 60million will be unable to drive. Then I'd estimate ~1/3rd of the people who can drive do drive. Then you have to account for internet access etc.. So it could be as many as 1/5th of the people who are going to be affected signing. Yet the PM doesn't do anything.
2) We vote representatives to make choices for us. If we want something different, we vote for people who will do what we want. We don't get to make the choices ourselves - that's what our entire political system is about. Is it right we try and have an input now?
So, will this make a difference? Is it a good idea? Is it a waste of money or is it worthwhile, if just so that the PM can view public opinion?
