Sooner or later, someone somewhere is going to catch on to the fact that whoever is updating the Number 10 Twitter account is having far too much fun - answering questions, being rational, civil and connected - and is going to make him/her stop. 

At which point I can say, “I told you so.” 

And also “Would you like a job?”

This leads to what should really be a longer post about how any political statement longer than 140 characters is too long, and can therefore safely be dismissed as puffery.
