Why was this bumped from the front page?

I'm not sure. The usual answer is that the ranking algorithm determined it should be downgraded. Why does it show up just fine in Firefox, but really terribly in Chrome (all unstyled, plain text, no images loaded, links don't work correctly)?

Maybe because it's basically an ad?

You mean a highly informative and thought-provoking piece about revolutionary technology and roadblocks to its mass adoption - which references a future product not yet available for purchase? I'd read these kind of "ads" all day, but they are too few and far between.
