I'm not saying these tech explorations are bad, they just need to have a big fat disclaimer "don't try this in prod" and preferably a reference implementation of how it would be done "properly".
If everyone is worried that the tech is too scary or unstable or "wrong" TM, then we will never push the web forward into new territory. Remember when all form submissions forced a page refresh? If people were too afraid of front-end validation and AJAX calls then this would still be the reality.
Any implementation could be torn to shreds.
Because that's how the evolutionary, competitive nature of technology works. Nothing is "right" or "wrong", to use the scarequotes so in fashion, but is from a perspective and position. If things needed disclaimers around here -- as if we're all idiots, or worse jaded cynics -- then I think it would be a bad day for HN.
But of course, houndres of insane trick-focused css gurus churning out millions of crazy tech demos... Surely someone will find out some novel, more useful technique that we conservative programmers will begin to use for making the boring shit we do less burdensome. So I'm all for it really, despite my initial negative tone.
