It’s time to stop talking, and start… umm… talking. Comment is free, our new superblog, launches today, bringing some of the sharpest minds to the blogosphere for the first time. We’ve got a remarkable list of contributors lined up to make their blogging bows as the week goes on.

Thus far, everything about this has been a departure. There’s the sheer number of bloggers (more than 200 so far, which more than doubles our blogging roster in one go). The groundbreaking design by the GU design team, aided by Guardian design chief Mark Porter. The complexity of the Movable Type backend being wrangled by Mr Hammersley. The integration with GU’s registration and content systems, which saw pretty much every GU developer pitch in over the last couple of months.

Now, beyond some tweaking, it’s down to the bloggers and the Comment is free editorial team led by Georgina Henry, formerly deputy editor of the paper. Building these things up is always a slog, as Emily Bell wrote on Saturday. But - even if I say so myself - it’s off to a flying start today.
