Is it possible the UK government's e-petitions system can actually have some benefit? After 30,000+ people signed the e-petition about the treatment in the 1950s of Alan Turing, one of the world's greatest mathematicians and computer scientists, leading directly to his suicide, Gordon Brown made this statement. Number 10 even made it the top story on the opening page (at least on 2009-09-11).
Of course the question is will Number 10 now re-think their rather poor answer to the e-petition about Bletchley Park, which is where Alan Turing undertook all his code breaking work during World War 2. (20,000+ people signed this e-petition.)
