>What would you do to create 100s or 1000s of these that are good!

Hey Ed,

I'd combine mTurk and SuperListz.

Get humans to write alternative sentences, then use Superlistz to dedoop even more. Super Listz does pretty much anything any article spinner does.

Having said this, using a program designed to specifically do this may save you a step or two.

I think Glenn Leader comes around still, check out his Artifact.
