How many active silver surfers are there?

 The on-line petition on the Number 10 Website to save the London Freedom Pass for those over 60 has under 14,000 signatures - yet the over 60s are more likely to vote. Interestingly I had not heard of this petition until I received an e-mail ten minutes ago. Is this symptomatic of a disconnect between the concerns of the blogogracy and those of real people? Or does it mean that Londoners are ready for savage public spending cuts - even if they directly affect them and their parents?
