I seem to remember a very similar posting from abtests.com last week. I would hope that people don't expect that you can magically copy the results of someone else's A/B test to your own domain.
It could just be that I am noticing the phrase since I read about it, but it would be a strange coincidence to see the exact wording so often.
I'm sure they don't think that a featured test would result in identical results on a different site. But opening up data like this for peer review and replication is a good thing.
Edit: Oh. dcancel said as much, just above this.
We at ABTests.com are simply trying to get more people to incorporate A/B Testing into their development process.
Thanks for the feedback, we appreciate it.
