I follow Scoble on Twitter and am subscribed to his blog.

The reason - he breaks tons of great stories, and has a lot of interesting interviews with people from the industry. I've heard about a lot of new startups/products for the first time through him, and they're always interesting.

Not sure how it came about, but that's the reason I follow him now.

(I've also met him briefly in real life, he's a really nice guy).
