Has anyone tested any of these? I'll show you mine if you show me yours -- A/B tests, that is.
Off the top of my head: blue links beat the stuffing out of "designer friendly" links back on my old site. I'd be astonished if I still had the numbers anywhere, since I don't remember blogging about it and it was over two years ago.
I don't have an A/B test to show you this, but trust two years of look at CrazyEgg: it is absolutely, positively, undeniably true that user engagement is centered above the fold. If your call to action isn't already above the fold, put it there, watch as you get extra free conversions. (Incidentally, I put a couple of them through the copy on my home page, on the theory "Why make people scroll back up if they've read to the bottom?" Every time I add a button, the total conversion rate increases.)

That's an interesting statement. That's what I would expect, on the basis of consistency with the behavior of other sites. What is the experience of other HN readers? Have you ever done a test of link colors?
Edit: Reading through Nielson's site again after a long time, I recommend it highly. I think the article about paper prototyping is particularly useful: http://www.useit.com/alertbox/20030414.html
Great post. I never thought about the direction of people's faces but I wonder if this had anything to do with the fact that it was a (cute) baby. What happens if your website does not deal in babies? But I bet the same thing applies if you have a mascot. Have their face point in the direction of where you want attention. And even if you don't have a mascot, just insert random cute puppy or kitten and have it face your text/product.
