Clubbing and dance music blogs
Voltage is an electro/electroclash blog with some strong opinions. As a closet metrosexual hidden in the body of an unfashionable MOR funky house lover, I can highly recommend it.
Dirty Funky Sexy is a club night with big plans. They have an Ibiza week in a hotel coming up and it's based it's website around a blog and forum. This level of interactivity is where things are going.
Disco Disciples is a clubbing blog I have just come across. It's intelligently written. More clubbers should have blogs like this one.
