For those new to this chart, it’s based on rankings published by web metrics company Alexa, which measures visits by users who have the Alexa toolbar installed. As that’s mostly bloggers and techies, the chart is probably biased towards blogs which are popular with other bloggers, or tech-heads.

The definition of what is a blog as opposed to a website is becoming blurred. Some of the sites above are commercial ad archives, or the online versions of news-stand ad mags, which I'm now including for the first time. As long as the content is updated dailyish, and the blog portion of the site is separately measurable, I don't see why they shouldn't be in here.

Some people find the chart boring, others say it helps them discover new things. Me, I've just always loved charts. As a kid, I pored over the pop charts, and football league tables. That doesn't make me a geek, does it?

An ↑ means a blog's traffic has gone up by 15% or more in the last quarter, and a ↓ means it's gone down 15%.

UK means UK-based. Ad blog means ad blogs not marketing or PR blogs. I'm only counting English language blogs.

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