Hooray for A/B! I like that you include the written acknowledgement that you sound pretentious, I think that actually adds credibility by having a sense of humor about it and recognizing that it's a thing people are doing. Something I didn't mention is that when someone sort of takes the piss in that manner, it actually positively affects the way I feel going through the rest of their site because at least I know they've got a good attitude and are probably fun to work with.
