I've been working on some code to parse the shapefile format, which specifies some fields in big-endian and some in little (I have no idea why), but the binary package has made it really easy to deal with.
Agreed that the web doesn't have any "magical properties", but it has the "Worse is Better" survival characteristic; or at least it did in its early days. I think the web's continued dominance depends on the extent to which it retains those characteristics.
I think the snake-oil nature of (much of) SEO stems from the fact that it's difficult or impossible to measure in an accurate, unambiguous way. Since A/B testing includes measurement by its very nature, I suspect it will be more resistant to snake oil.
