Many websites are built for mobile devices these days, but you'll still run into the occasional page that refuses to run. Wouldn't it be nice if you got a heads-up before you wasted a click? As of today, you will: Google search now warns you when a site isn't likely to work on your hardware of choice due to incompatible content, such as Flash. You can still visit if you're convinced everything will be A-OK, or if you just have a masochistic streak. However, the new search policy may leave some site designers scrambling -- now that Google is discouraging mobile users from visiting pages that insist on proprietary plugins, companies may have to switch to web standards like HTML5 if they want to get your business.
