Apparently "even if a blog you like has already been nominated, it's worth your time to nominate that blog again - only those top blogs with the most total nominations will make it into actual voting. Nominations will be accepted until midnight EST on December 3rd."
The top prize is $500 worth of i-Tunes (and I haven't even got an iPod, but, hey I won't knock an award).
So if you feel like adding to my nomination, skip over to this page to see who is in the running and nominate (London Underground Tube Diary) and any others of your choice by send an email to email@example.com by 3rd December. Then in a similar way to the Bloggies those that get the most nominations reach the final and voting for those finalists takes place from 5th December - 26th December.
For the judges' purposes, "an urban blog is a regularly updated blog site with over half of its content focused on a city, cities in general, city living, urban lifestyles, urban travel, or something of the sort."
