PC World describes the methodology behind the report:
The figures were gleaned from an analysis of real-time traffic passing through the company corporate proxying service, designed to filter out the worst content. A total of 614 sites were chosen at random from sites reckoned to have blogging as a significant activity.

What is does indicate is the extent to which the Internet has become a channel for what Nadir suggested might be a long tail of minority interests that encompass interests others would deem ‘offensive”. Companies needed to be aware of the issue, however.
