Help me understand Bridgestone RB-1

[chakatrain]

So...I've read some reviews about the Bridgestone RB-1; it seems like the frame has a lot of fans. What's so special about it? I've been really enjoying reading about bike craftmanship and history lately and realize how many holes of ignorance exist in what I call my knowledge. Would be mighty grateful for a fan of this frame to share the love.

this thread in the classifieds forum got me thinking about this.
