Post box
The post box starts in a collapsed state to save screen space.
Users can click the three icons above the box in either the collapsed or expanded state to choose to create a microblog post, a question or a private message.
When the user clicks inside the post box, it expands to give more room for entering text.
The post box has all the same functionality as the activity stream web part. File and link attachments can be done and hashtags are automatically recommended.
Links included in microblog posts and questions automatically try to retrieve a thumbnail image and a synopsis for that page (new feature in 3.0 – see below).
Similarly, creating a question provides the same options available in the activity stream web part including creating a poll.
When the user posts a microblog or question, the my stream column should refresh to display it if the display filter is set to a view that includes that item.
