Leveraging the YouTube API - MyFaith.com

On our recent project MyFaith.com, we made extensive use of the YouTube API to allow users to  upload videos from MyFaith into their individual YouTube accounts and also add videos to MyFaith from their existing YouTube videos.  Why re-invent the wheel when YouTube already provides free video hosting and has over 100 million monthly users? 

The site has many other great features including video rating, commenting, embedding, sharing videos, favorites list, etc.  Check it out at www.MyFaith.com
