Yes, this post makes a lot of assumptions. I don't understand why I would question the motives of people who just want to use my site/product to complete tasks as simply as possible.

And binary thinking? Just because I do one A/B test doesn't mean the matter is settled. The "winner" of the first test can be tested against other options, whether it's right away or 6 months down the road. It goes on and on & hopefully we get closer and closer to "perfect".
