The youtube shortcode fails when viewing the blog in Google Reader. The embedded videos appear as thumbnail images instead. When clicked, they open a new browser tab to the original blog post, where the user must then locate the video again and click to start. In other words, it takes my viewers 2 extra clicks to watch any of my videos through Reader, which is what 90% of my readership uses. Is there a way to "opt out" of using the youtube shortcode? I would rather use the iframe code in this case, which seems to work just fine for me.
