One of my favourite blog sites to visit is Honeyee, which publishes a web magazine as well as gathering a diverse set of blog contributors together. A lot of it is in Japanese, but there are English-language blogs from influential musicians (Eric Clapton, John Mayer) artists (Kaws) and fashion label/design types (Jeff Staple, Keith Hufnagel).
Great visual interface too, with contributors colour-coded according to recent activity.
