I thought long and hard before including Ads Of The World for the first time. You could argue it's more a commercial website than a blog. Then again, they do have a blog on there. The line between a blog and a website is getting blurry, since most commercial websites now host bloggers, and many blogs are now also commercial enterprises.

A simpler (because purely mathematical) decision was the well-deserved first appearance on the chart for Britain’s own Neil Perkin, whose sparky Only Dead Fish (swim with the water) blog has grown rapidly of late.

For those new to the chart, I might just re-cap how it’s calculated. The chart is based on rankings published by web metrics company Alexa, which solely measure visits by users who have the Alexa toolbar installed. As it’s mostly bloggers and techies who have that, the chart is somewhat biased towards blogs which are popular with other bloggers, or tech-heads.

Some people find the chart boring, others say it helps them discover new things. I tend towards the latter view, but there isn’t enough movement to justify doing it monthly so I am now doing the chart quarterly.

An ↑ means a blog's traffic has gone up by 25% or more in the last quarter, and a ↓ means it's gone down 25%.

UK means UK-based. Ad blog means ad blogs not marketing or PR blogs. Paul Colman is now a planner at W&K and doesn’t blog though he occasionally blog-sits. Russell Davies no longer blogs about advertising but is still unmissable reading. I'm only counting English language blogs.

If I've missed anyone out, please tell me and I'll put them in next time.
