I initially thought there were still no UK blogs in the Top 25, but I must correct that mistake, because two have in fact snuck in, at 24 and 25. Welcome to Optimism is back, and the excellent Adliterate this month makes its debut in the World chart. Just try keeping Richard Huntington out of that edit suite now.

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%.

UK means UK-based. Ad blog means ad blogs not marketing blogs, so that excludes Gapingvoid. Although Paul Colman is now a planner at W&K, he doesn't class the wildly popular Life In The Middle as an ad blog and Russell Davies no longer blogs about advertising. He does write about it in Campaign though, so I hope he still likes it. 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.
