Too bad the API is still "coming soon", but it is good news that they're working on it. I'd love to have access to that data without having to log in, and to build apps around it.
I smell rushed push out of features to ward off defections to Yahoo's competing service. They even promise their API is 'coming soon', a feature that set yahoo's offering apart. Gee I love competition. Let's hope yahoo stays independent a while longer to cause a few more of these chain reactions.
Can't wait to play with those, but of course they're not activated yet in my account. The Adsense integration is huge and will probably lead me to dynamically include ads depending on the provenance of users (Like, if it shows that Diggers never click an ad, why bother?).
Now if it could provide a real time list of the latest 100 or so visitors... it would be perfect.
