Kevin Rose and the crew at Digg.com have just launched an iPhone optimized version of their site (http://www.digg.com/iphone). It’s really really cool.
It’s one of many sites that take advantage of Joe Hewitt’s iPhone User Interface template. This means that it uses the inherent interactions found in the iPhone.
It only shows the recently popular stories but, unlike Digg River, when you click on a story you get to see the story description and the top 5 comments. It looks really nice.
They did the whole site in 48 hours. Kudos to them!
This gives me a few ideas for my own iPhone optimized apps.
