"Instant Preview" has to be the single worst change that google ever made to their search pages. I'm at the verge of switching to bing for a while because I keep triggering these god-awful popups by accident.
Whenever I read stuff like this, it's painfully obvious that browsers were not designed as the universal application runtime.<p>Why are we using technologies designed for displaying documents to write applications? Because they're there, I suppose.
It's interesting that the previews are made available using JSONP. This should technically allow other web sites to also retrieve and display them.<p>The post doesn't mention whether Google allows this, though, or whether they expect the interface to remain stable.
Ok, but didn't have the one piece of information I was hoping to learn. Does anyone know what Google is using to render the preview images?<p>Now that these images are in search results, everyone will need to make sure that Google renders their site well.
