Apple rumored to be adding photo sharing, commenting, video features to iCloud

Apple might just be ready to add photo and video sharing and commenting to iCloud, most likely at WWDC 2012 this June. According to The Wall Street Journal:

The new features, expected to be announced at Apple's world-wide developer conference beginning June 11, will allow iCloud users to share sets of photos with other iCloud users and to comment on them, these people said. Currently, users can only store one set of photos in iCloud through a feature called Photo Stream, which is designed to sync those photos to other Apple devices, not share them.

Apple is also working on a new feature that will allow iCloud users to sync their personal videos via iCloud, these people said, as well as allow users to access "Notes" and "Reminders"—two of its apps for jotting down quick thoughts—through Currently, those items have to be accessed via apps for those features.

iCloud's predecessor, MobileMe, included a gallery feature that provided sharing functionality, but it was not migrated to iCloud. When Apple introduced iCloud, they included Photo Stream, which handles backup but not sharing.

The recent, apparently inadvertent publication of an iCloud beta site also showed Notes and Reminders web apps that seem likely additions to iCloud.

WWDC 2012 is less than a month away. What else should Apple be adding to iCloud?
