Sure. But the A/B tests aren't testing things like "which color combo leads to faster comprehension and response among people with colorblindness" and more like "do we get more money from our customers if we put the sales banner above the corporate logo or below it?" The former situation could be beneficial to the user while the latter is beneficial almost exclusively to the site operator. Oh wait. You were being snarky. I see it now. Very droll. Yes. Didn't we put a clause in the Terms of Use document saying users agree to be our guinea pigs for various inhumane interface experiments forever!?
