The clever people at MySociety have bought you a new service, DowningStreetSays, which is a kind of blog of the press briefings given by the mysterious PMOS every day at No.10 Downing Street. Whilst it’s not official, I imagine it uses the official service as a base, which you can find on the offical site. The main differences between the two are that with the MySociety version, you can leave comments and it’s a little easier to track back through the archives (because of the blog style format). Rumour has it that there are yet more similar projects in the works.
