I did this a while back for fun on my blog, but now there’s an entire website devoted to it. It’s a great idea, and I’m enjoying reading the other p.99′s out there: http://page99test.com.
Try it, see what you think. Mine (from Symbiosis) is uploaded, but there’s no way to pick and choose which p.99 you get to see. That way friends can’t artificially boost your reviews.
