Indeed, how can that ever be possible since only allows officially approved widgets (Youtube, Google Video etc) to be embedded directly due to security reasons. All other widgets are out of luck and must be added through plug-in allowable only in paid WordPress hosted site.
But really, how cool to find out a service (Thanx to WordPress.com forum) that breaks the spell and makes the impossible possible ? Precisely with , any embeddable flash widget can now appear in WordPress.com as law-abided citizen.
Just take the following widgets that use to appear on paid WordPress hosting service. Not anymore as evident from this post which hosts on WordPress.com
Somehow Vodpod ‘magically’ translates the widget embedded code into Vodpod’s shortcode that works perfectly in WordPress.com.
Yes, you can do it too.
