There are currently two similar API methods in which microblogging is possible:

• Action - post an action on a context with included message
• Announce - scrobble an experience on a context with included message

Included messages are optional. Two important actions, which may not be apparent are comment and reply. Comment is the default action and is simply for making a comment on a context (title/user/creator) page, though it is posted into the stream. Reply is an action between users denoted by @. These both fall under the Action method.

Announce is a special-purpose event, explained more in detail on the Events Streaming page.

Because these methods are available in the API, they are also available for 3rd party application development (using REST/JSON for posting). Retrival of action-event activity is also currently available in XML format.
