Video/audio is problematic along with <object>. It's memory intensive -  
especially on a blog with lots of blog entries. The practice right now is  
an image link to the video. Something that's used more and more is a  
rel="enclosure" link that is transformed to an <object> by javascript when  
clicked (my preferred way of embedding video).

And rel-enclosure is not just for audio and video. Using <object> is not  
always desirable - embedding zip files, photoshop files and PDF's with  
additional information directly in the page is rarely a good idea (a quick  
way to break the browser, I bet). they are still enclosures.
