Thanks! I happend to have that one on my facebook, definitely a good one. Also, since I don't want this thread to just be about me, here are a few that I have

2headed Snake - Illustration
Vicious History - a lot of good traditional tattoo work
I Need Some Rest - lot of cool horror and comic illustration

Abduzeedo, ffffound, The Hundreds (it's the company's blog but Bobby Hundreds always features art and design oriented stuff) and my personal favorite; Pantonism.

iso50, core77, thefoxisblack, abduzeedo, alistapart, creative bloq, swissmiss, unmatchedstyle, smashing magazine, and a few others I can't remember. Most are web design related

Not necessarily a blog, but also has nice finds(meta crawler that pulls from ffffoound and other blog sources)

Here's the tumblr version of Boooooooom: http://booooooom.tumblr.com but its not as good or updated as frequently as the original.

Also: http://grainedit.com & http://blog.iso50.com. I'll also check out http://rhizome.org every once in awhile.

Those are the first that came to mind.
