IMHO, the establishment of the TSA's blog is an acknowledgment that things are really bad on the front lines.

41,000,000 potential air passengers a day dropping out - and a big reason is the "security" hassle. That's not a drop in the bucket. Both the TSA and the airlines need to take heed.

FWIW, the TSA does seem to be making some changes in response to thousands of complaints from the traveling public. Will those changes be positive or negative - time will tell.
