I expect it to provide useful information, not make null statements.

I've always read that sentence as saying "this is one of a
series of daily status reports, and one should read them in
order -- they don't necessarily stand alone". Can't say I've
been happy with that mindset and writing style, mind you.

Now, why should we accept tripe from NASA?

This is the NASA PAO we're talking about, right? ;-)
