Interactions
All the News Stream article displays within SharePoint allow access to the SharePoint tag and note control and easy sharing via the activity stream.
Tag It
The Tag It link brings up the SharePoint control used for adding tags and notes to links. The story link is automatically selected, so the user simply enters a tag and/or a note. This SharePoint control supports auto- completion of tags as shown below.
Share It
The Share It link displays a text entry box where the user can add commentary and also direct the link to specific users or groups (exactly like a microblog message including the auto-completion behavior). The link to the story is automatically pasted into the message.
