Everyone is talking about this service that launched yesterday, so I am going to do this posting before it becomes old news.
SplashCast is "a service that allows you to play dynamically updated channels of content on your web page, blog, or social network page (like MySpace)."
"SplashCast enables anyone to create streaming media ‘channels’ that combine video, music, photos, narration, text and RSS feeds. These user-generated channels can be played and easily syndicated on any web site, blog, or social network page. When channel owners modify their channel, their content is automatically updated across all the web pages ‘tuned’ to that channel."
