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 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.
