NewsGator keywords feature
When the NewsGator Keywords feature is activated in a community, the tabular list displays in the community (for Documents, Wikis, Tasks, etc.) gain a Tags and Notes column.
Clicking on the tag and note icon in this column brings up the control to view all the tags and comments on the item and to add more.
This makes it much easier to add social data to your document and list libraries, and to view the same.
(Another easy way to add notes to a list item is if your organization has opted to have comments on stream events for adding or editing list items automatically become notes on the list item.)
When displayed in a document library or wiki library, the Tags and Notes column also tells how many notes each document has (referring to them as comments).
This makes it easy to find the document-centered discussions in a document library.
