Jonathan Schwartz wrote a letter to the US Securities and Exchange Commission about using the Internet (i.e. blogs) for disclosure:

In your letter of November 2, you raised potential challenges to permitting blogs and corporate websites to be used to satisfy Reg FD's "widespread dissemination" requirement. Specifically, you inquired whether “there exist effective means to guarantee that a corporation uses its website in ways that assure broad non-exclusionary access, and the extent to which a determination that particular methods are effective in that regard depends on the particular facts.” Some of the comments to my blog echo the same concerns: critical company information could be difficult to find, accessible only with a registration or technologically obstructed.

We understand these apprehensions, but are confident that they can be addressed with clear directives from the SEC on the presentation and accessibility of information on corporate websites.

The letter has specific proposals about how to do it.
