Very few of my clients use or ask for this capability. Most of the people I know prefer to use the RSS feeds as a quick preview option.

As one client put it...

"If readers want to see video, audio, and pictures, they should come to my site. There is no need to replicate everything in an RSS feed. When readers view an RSS feed, they are missing out on the many socialization and member perks I provide on the site."

Another client had this to say...

"It's just one more thing I will never use and will clutter up my database."

Those comments pretty much sum up the way most of my clients feel. Like I've said in the past, just because you CAN doesn't mean you SHOULD.
