I've read it and followed through to the end. Works just as shown in the snapshots. I wouldn't class this as intermediate though, but I guess it can be.
Intermediate would be more like
i.e text text tex ... readmore(<- link) or the image is activated to popup to a larger view.
But i must say, I really liked it, it gave me some ideas (i'm in a block right now). like porting it to php, jsp and or aspx, the possiblities are endless.
Nice and really working tutorial. (4 stars, because i do not really think it was intermediate).
