First I have to say that this was a tough assignment, tough because I didn't want to choose just one award winner to look at and play with. I actually peeked at quite of few of them and was impressed by what I found. For this post, I'll just address Pandora, a music oriented site that lets you create your own radio station, just by entering the types of artists or songs you already like. It then adds similar projects to a list that you can then edit, listen to, or delete entirely. Very simple, very nice. At this point I only see the personal application of this one, but if we added sound to the pacs, perhaps patrons could choose pre-made lists of certain genres to listen to. Yeah, yeah, I know, the library is for quiet study ;)
