"[Q] From Lindsay Chalson: “I was wondering if you could tell me where the phrase pie in the sky came from?”

[A] It comes from the Industrial Workers of the World, the anarchist-syndicalist labour organisation formed in the US in 1905, often called the Wobblies. The Wobblies concentrated on organising migrant and casual workers; one of the ways in which they brought such disparate and fragmented groups together was by song. Every member got a little red book when he joined, containing parodies of popular songs or hymns (the book had a motto on the cover: “To Fan the Flames of Discontent”). One of the early ones, predating the IWW, was Hallelujah, I’m a Bum."

..."The song was a parody of the Salvation Army hymn In the Sweet Bye and Bye:

Long-haired preachers come out every night,
Try to tell you what's wrong and what's right;
But when asked how 'bout something to eat
They will answer with voices so sweet:

CHORUS:
You will eat, bye and bye,
In that glorious land above the sky;
Work and pray, live on hay,
You'll get pie in the sky when you die. "

"Keen observers had spotted what appeared to be the outline of a vast city on the floor of the Atlantic Ocean.

But the criss-crossing lines, located 600 miles west of the Canary Islands, were today explained by Google as sonar data collected as boats mapped the ocean floor. "

is it possible to only use the algorithm to send posts to editors so they can review it before it gets posted to the front page?

I keep thinking that it is the automation that is bringing down the quality that folks are used to on this blog. I just don't know how an automated program could ever determine whether something is actually "neat."
