Returning to the central theme, bloggers are not evaluated on the accuracy of what they write, but who links to them. Linking may relate to approval at some level, but it is hardly analogous to peer review. Peer review, to first order, is about the plausibility of the logic, not about whether the underlying experiments are accurate. This deficiency was abundantly manifested in the evaluation of the work of Schon and Hwang (see for example 88 JPTOS 239).
Based on "who links to IPBiz," Technorati gives IPBiz a low authority number of 25.
