According to ^[2] The Wall Street Journal, Apple plans to announce an upgrade to its iCloud service at Worldwide Developers Conference next months. The refreshed service will allow iCloud users to share photos with each other and comment on them. Now, users can only store photos via a Photo Stream feature that is capable to sync photos with other Apple devices, but not to share them.

Also it seems that Apple is going to update the Photo Stream to support videos so that users can access their personal videos via iCloud. The report also claims that new icons Reminders and Notes found on a beta.icloud.com site last week are designed for a new functionality to sync these services with iCloud, which will allow users to access them through both the iCloud site and dedicated apps.
