Ideas Stream
The Ideas Stream shows you a real-time feed of activity from users and ideas that you are following, which includes any activity on ideas that you've posted (e.g., if a user votes or comments on your idea).
When a new event is added to the idea stream, you'll be able to view the comment, idea, or user details by clicking on the appropriate blue links on the tile.
