I think I'm generally more interested in the small-time blogs than the well-established blog. Well-established blogs with a solid following can succumb to group-think in the guise of introspection.
Sometimes, a newer blogging voice can present a different perspective on existing topics:
Found from a @implu tweet Retire your desktop: The Future:
– Greenspan's perception of the Information Technology bonus (in terms of productivity)
– Wall Street's irrational exuberance leading to the DotCom Bubble.
– Gen Y's unintentional leadership of humanity into freedom.
