Three new blogs this month.

In with a bullet at No.1 is Houtlust, a site I've only just become aware of but which is massively popular - even bigger than Adrants. It covers communications for not-for-profit advertisers. Must be a highly valuable resource for people in that sector I would say.

In at No.9 is Duncan's TV Ad Land. Duncan Macleod is an advertising enthusiast who lives in Australia. He keeps a very detailed record of what he considers to be the best new work, with commentary too. For a while I wasn't sure whether to class it as a blog or not, but he does post every day, so why not?

Coming in at No.19 is the fast-rising AdArena, from Radovan Grezo and his team in Slovakia, again covering 'best of new work', with a specific emphasis on new media, guerrilla and viral campaigns. Radovan sent me a wonderfully complimentary e-mail about Raining Time, so I'm happy to welcome him to the chart.

So three blogs drop out of the chart - Scamp, Hidden Persuader and BrandFlakes for Breakfast.

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

I've removed AdScam from the UK chart, as I've belatedly realised that George Parker is based in the US, so he doesn't count. Fun blog though.

New in at No.8 this month is Meme Huffer by Jason Lonsdale, a Kiwi planner transplanted to London. He keeps an enjoyable and eclectic blog, with the tagline "a deep breath of ideas, culture & stuff".

UK means UK-based. Ad blog means ad blogs not marketing blogs, so that excludes Gapingvoid. Paul Colman doesn't class Life In The Middle as an ad blog and Russell Davies claims he no longer blogs about advertising, though the odd observation about our benighted industry does creep in. Also, I'm only counting English language blogs.

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