Useful to me, probably useless to the vast majority. This short list is my way of bookmarking some of the more interesting sites I check out every so often for fun and learning.
In no particular order,
Scott Adam's Dilbert Blog. I like his wit and sense of humor and his far-out 'theories'.
Guy Kawasaki's Blog. This one speaks to the entrepreneur in me.
HDForIndies. This one speaks to the geek in me. In binary, no less.
Presentation Zen. This one speaks to the zen master in me. Heh ... right.
Kenny Sia's Blog. Fellow Kuchingite and friend of a friend who's now a friend.
ProLost. Stu Maschwitz's blog. Geek alert! Very high concentrations of geek content.
TUAW. The Unofficial Apple Website. Not really a blog, per se. Speaks to the Apple fanboy in me.
Cinematography.com. Ok, this is so totally not a blog but it's THE place I go to everyday to read forum posts. Occasionally, I post, too.
CGTalk. Every CG Artist's destination for answers to such mundane questions as 'How do I get Renderman to render blackhole matte passes using RibBox?'
So there.
