All the parties had been promising new powers since the summer, but the three parties disagreed about what they should be and it was frequently criticised that voting 'no' meant that you were just crossing your fingers and hoping that they'd sort it out. So Gordon Brown proposed a timetable to stop it being kicked into the long grass if there was a no vote, and the three UK leaders signed up to it (I think the three Holyrood ones did too, but can't remember if that was to the Vow or not).
So many people voting no but still wanting more devolution made their minds up some time ago before the vow. I realise that the parties were a little late with the first step, but I'm sure it was sorted the very next day. You might call that the breaking of the vow because yes are determined to jump on them as soon as they appear to screw up, but most people I think don't really care whether it was signed on Friday or Saturday, they just wanted to be sure it was going to happen.
I still believe it will happen but even if it takes longer than expected, I'm happy with my vote. The risks and likelihood of Yes being wrong about the currency/EU/Nato/etc were much greater and the consequences far more severe IMO. YMMV.
It's great to hear the food banks are not being forgotten now that they aren't being used by politicians to make points.
As for devolution/changes to politics in England, I think Cameron is wrong to try and rush changes through. I think that the people of England have to be consulted about this. As much as it's great for some decisions to be made locally, there is also a benefit to being able to have national services that there isn't a postcode lottery for. Often the whole is greater than a sum of its parts. E.g. with the postal service, being able to post a letter to anywhere in the country for the same price. You can see the damage caused to rural businesses and people by huge delivery surcharges.
I'm not sure about how far devolution in Scotland should go, for similar reasons. There is clearly an appetite for more powers and I think some may make sense, but I don't want to become an entirely different country to the rUK in all but name either.
