Bloggers may take advantage of the FOIA

Well that's a bit of an overstatement. If a blogger has a large enough readership (not defined) then they will be able to make FOIA (Freedom of Information Act) requests and such a request "has" to be honored.

Freedom of Information Act Amendments of 2007 - Amends the Freedom of Information Act (FOIA) to prohibit a federal agency from denying a requester status as a news media representative for purposes of determining FOIA request processing fees solely on the absence of institutional association. Requires an agency to consider the requester's prior publication history or stated intent to distribute information to a reasonably broad audience.

According to The Gavel, this bill to amend the FOIA has been passed by the House. Come on Senate.
