A review of the medical weblog, Clinical Correlations.

While Internet use is ubiquitous and its facets numerous, the blog is notable as a way to combine the speed of Internet delivery with more extended discussions either of a personal or professional nature. Because so many of the scientific information sources are behind “pay-walls”,1 it may not be easy to access reliable, substantive literature without affiliation. Even when material is freely available, it may not come in a format that is preferred. Professional-related blogs can fill that void with timely and extended depth of information, and they can build on the known body of knowledge without extensive background repetition for each entry. Basically, blogs can combine factual content, rapidity, and fresh viewpoints and can be tailored to meet users’ needs. It is no wonder that 38,000 blogs are created daily.2
