All these things that I have done

I'm not so sure that PR is really the answer. After all Germany *does* have a PR system. The author of the article you linked to sees Germany's coalition as part of the problem, and generally PR systems are far more likely to produce coalitions than first-past-the-post. I think the author of the article makes a good point about needing to get people more involved with their communities, but I'm not quite sure how that could be achieved...
