The latest site from those nice people at My Society is called Hear From Your MP. The idea is simple (like most good ones) - you give them your name, email address and postcode and they add you to a list of people interested in hearing from your local MP. When they get twenty names on that list they sent an email to the MP saying "twenty of your consituents are interesting in hearing what you are doing". That email is repeated when higher targets are hit. You can read more of the details here. You can also see which MPs have responded.
It's all part of My Society's ongoing campaign to use the internet to make MPs more accountable to their constituents. Which has to be a good thing.
I signed up. Apparently I was the 10th person in Burton on Trent, and the 45th person in Oxford. No surprise there.
